Drishti.

The Sanskrit word दृष्टि (Dṛṣṭi) means sight, vision, gaze, or way of seeing. It comes from the Sanskrit root दृश् (dṛś), meaning "to see" or "to perceive."

Depending on the context, dṛṣṭi has different meanings:

Physical sight – eyesight or looking at something.

Guru dṛṣṭi means "the guru's gaze."

Mental outlook or perspective – one's way of understanding or viewing the world.

Sama-dṛṣṭi means "equal vision," seeing everyone with impartiality.

Divine or spiritual vision – the ability to perceive truths beyond ordinary sight.

In the Bhagavad Gita, Krishna grants Arjuna divya-dṛṣṭi (divine vision) to behold the universal form.

Evil eye – in common Indian usage, dṛṣṭi can refer to the "evil eye" (dṛṣṭi doṣa), and people may perform dṛṣṭi nivāraṇa (removal of the evil eye).

In classical Indian traditions such as yoga and dance, dṛṣṭi also refers to the direction or focus of the eyes, which helps develop concentration and expressiveness.

Thus, dṛṣṭi is much more than eyesight—it encompasses vision, perception, insight, and one's entire way of seeing reality.

The defence technology finding an important civilian application.

Dr. Shubha Venkatesh Iyengar, a senior scientist from CSIR–National Aerospace Laboratories, contributed to India's strategic defence programmes, including work associated with the Agni missile programme. She later led the development of Drishti, India's first indigenous runway visibility measuring system.

What does Drishti do?

Drishti continuously measures Runway Visual Range (RVR)—the distance a pilot can clearly see along the runway. This is crucial during:

Dense fog

Heavy rain

Dust storms

Smog

Low-light conditions

The system sends real-time visibility data to air traffic controllers and meteorological officers, enabling pilots to make safer landing and take-off decisions. 

Why is it important?

Before Drishti, India largely relied on expensive imported runway visibility systems. Drishti:

Is designed specifically for Indian weather conditions.

Costs significantly less than imported systems.

Requires less maintenance.

Meets international standards laid down by the International Civil Aviation Organization and the World Meteorological Organization. 

The technology was first field-tested at Indira Gandhi International Airport around 2011 and was later deployed at major airports across India as well as at Indian Air Force airbases. 

Dr. Shubha Venkatesh Iyengar received the Padma Shri in recognition of this pioneering contribution to Indian aviation safety. 

Her work is a powerful reminder that scientific innovations developed for national defence can also save lives every day in civilian life—quietly guiding thousands of aircraft through fog and poor visibility.

This too is an art.

 The Art of Quitting sounds paradoxical because we are often taught, "Winners never quit." Yet wisdom teaches that knowing what to quit is as important as knowing what to pursue.

There are two kinds of quitting:

Quitting out of weakness—giving up because of fear, laziness, or impatience. This generally leads to regret.

Quitting out of wisdom—letting go because continuing no longer serves truth, growth, or well-being. This requires courage.

Ancient Indian philosophy repeatedly praises intelligent renunciation. The Bhagavad Gita does not ask us to quit action; it asks us to quit attachment to the fruits of action. The real victory is not abandoning duty but abandoning ego, greed, anger, and possessiveness.

In everyday life, the art of quitting may mean:

Quitting a destructive habit before it becomes an addiction.

Quitting an argument when winning it would cost a relationship.

Quitting resentment that has become a burden.

Quitting comparisons that steal contentment.

Quitting the need to be right all the time.

Quitting work that has become unethical or purposeless, while continuing to fulfill one's responsibilities wisely.

A sculptor creates a beautiful statue not by adding stone but by removing what does not belong. Likewise, character is often shaped more by what we let go of than by what we acquire.

There is a beautiful Sanskrit saying:

त्यजेदेकं कुलस्यार्थे ग्रामस्यार्थे कुलं त्यजेत्।

ग्रामं जनपदस्यार्थे आत्मार्थे पृथिवीं त्यजेत्॥

It means: "Sacrifice one person for the welfare of the family, a family for the welfare of the village, a village for the welfare of the nation, and even the whole world for the sake of the Self (the highest spiritual truth)." This teaches discernment in choosing what to relinquish for a greater good.

The highest form of quitting is not giving up on life—it is giving up the illusions that keep us from living fully.

Life is not measured only by what we achieve, but also by what we wisely choose to leave behind. The art of quitting is the art of making space—for peace, for purpose, and for the Divine.

Astonishing.

The most fascinating intersections of ancient Indian thought and modern computer science. While the phrase "Panini Algebraic Matrix" is not a traditional scholarly term, it captures an important idea: Pāṇini created a rule-based, formal system for language that resembles the logic behind modern programming languages.

Pāṇini's astonishing system

Around the 5th–4th century BCE, Pāṇini composed the Aṣṭādhyāyī, consisting of nearly 4,000 concise rules (sūtras). These rules are not merely descriptive—they generate valid Sanskrit expressions through a precise sequence of operations.

His grammar includes concepts familiar to computer scientists:

A finite set of symbols.

Explicit production rules.

Variables and placeholders.

Ordered execution of rules.

Exception handling.

Meta-rules that govern other rules.

Economy of notation, using auxiliary markers (anubandhas).

This is remarkably similar to the formal grammars used today in compiler design.

Why computer scientists admire Pāṇini

Modern programming languages are defined by formal grammars. A compiler parses source code according to strict syntactic rules before translating it into machine instructions.

Pāṇini's grammar functions in a comparable way:

Input: a verbal root or nominal stem.

Rules are applied in a prescribed order.

Intermediate transformations occur.

The final output is a grammatically correct Sanskrit word or sentence.

Because every step is explicitly specified, the process is highly algorithmic.

Influence on modern linguistics

In the 20th century, linguists such as Noam Chomsky developed generative grammar, and computer scientists developed formal language theory. Although Chomsky's work arose independently, many scholars have noted striking conceptual parallels between his formal grammars and Pāṇini's system.

The notation used in compiler construction today owes much to the broader field of formal grammars—an area in which Pāṇini is regarded as one of history's earliest and greatest pioneers.

Was Pāṇini describing computer programming?

Not literally. Pāṇini did not invent computers or programming languages.

However, he developed one of humanity's earliest known formal rule systems—a system so rigorous that it can be implemented computationally. For this reason, many historians of science regard the Aṣṭādhyāyī as one of the world's earliest examples of an algorithmic specification.

It is therefore fair to say:

Pāṇini did not define modern computer programming, but he developed a formal, algorithmic grammar whose logical structure closely resembles the principles underlying programming languages, compilers, and computational linguistics.

For someone interested in the harmony between the Vedic tradition and modern knowledge, Pāṇini is a remarkable example. His work demonstrates that ancient India did not merely preserve sacred texts—it also developed highly sophisticated systems of logic, abstraction, and symbolic reasoning that continue to inspire linguists and computer scientists today.

Priyakaram

 Shodasha Upachara (Ṣoḍaśopacāra) worship—the sixteen traditional offerings made to the Lord. At temples dedicated to Lord Venkatachalapathy, including Tirumala Venkateswara Temple, these sixteen upacharas form the basis of daily worship, although the exact sequence and additional rituals vary according to the Agamas and the temple schedule.

The sixteen offerings are:

Avahana – Inviting the Lord.

Asana – Offering a divine seat.

Padya – Washing the Lord's feet.

Arghya – Offering water to wash the hands.

Achamaniya – Water for sipping.

Snana or Abhisheka – Sacred bath.

Vastra – Offering garments.

Yajnopavita – Offering the sacred thread.

Gandha – Applying sandal paste.

Pushpa – Offering flowers and garlands.

Dhupa – Offering incense.

Dipa – Waving the sacred lamp.

Naivedya – Offering food.

Tambula – Offering betel leaves and areca nut.

Nirajana (Karpoora Arati) – Camphor or final ārati.

Mantrapushpa and Namaskara – Offering flowers with Vedic hymns and prostration.

Daily rituals for Lord Venkatachalapathy

At Tirumala, every day follows a rich schedule that includes:

Suprabhata Seva (awakening the Lord)

Thomala Seva (adorning with flower garlands)

Archana (chanting the divine names)

Naivedyam (food offerings)

Kalyanotsavam (on designated occasions)

Dolotsavam

Sahasra Deepalankara Seva

Ekanta Seva (putting the Lord to rest at night)

Special significance of each weekday

Although the sixteen upacharas remain the foundation, each weekday has its own traditional associations:

Sunday – Worship for health and vitality.

Monday – Peace of mind and family harmony.

Tuesday – Courage and protection.

Wednesday – Wisdom and success in learning.

Thursday – Day especially sacred to Vishnu and the Guru; blessings for knowledge and prosperity.

Friday – A particularly important day at Tirumala, when the celebrated Abhishekam is performed to the Lord's main deity.

Saturday – Devotees pray for relief from difficulties and the grace to overcome karmic obstacles.

The rituals at Tirumala are performed according to the ancient Vaikhanasa Agama, one of the oldest surviving systems of temple worship dedicated to Lord Vishnu.

A traditional description of how Lord Venkatachalapathy is especially pleased on each day of the week. They beautifully associate each weekday with a particular seva (service) or aspect of the Lord's grace.

Sunday (Ravivāsara)

Kavijana Stotra Priyakaram

"On Sunday, He delights in the hymns and praises sung by poets."

The Sun represents brilliance and illumination. Devotees offer eloquent stotras, kirtanas, and devotional poetry. The Lord is pleased by heartfelt words born of devotion rather than literary excellence alone.

Monday (Chandravāsara)

Chandra Puṣkariṇī Snāna Priyakaram

"On Monday, He delights in bathing in the sacred waters of the Chandra Puṣkariṇī."

Monday is associated with the Moon, symbolizing peace and purity. The ceremonial bath signifies cleansing the mind and heart before approaching the Lord.

Tuesday (Maṅgalavāsara)

Śrīgandha-Candana-Miśrita Maṅgalodaka Snāna Priyakaram

"On Tuesday, He delights in an auspicious bath with water scented with sandalwood."

Sandalwood represents cooling, purity, and auspiciousness. The fragrant ceremonial bath signifies offering one's best to the Lord.

Wednesday (Budhavāsara)

Budhajanair Veditam

"On Wednesday, He is worshipped and realized by the wise and learned."

Budha signifies intelligence. This day emphasizes scriptural study, contemplation, and understanding the Lord through knowledge illuminated by devotion.

Thursday (Bṛhaspativāsara)

Akhila Jagannāthāya Darśana Priyakaram

"On Thursday, He delights in granting darśana to the entire world."

Thursday is the day of the Guru. The Lord blesses all devotees through His divine glance, reminding us that His grace is available to everyone.

Friday (Śukravāsara)

Nirmālya Visarjana, Suprabhāta, Thomāla, Ekānta Seva Niratam

"On Friday, He remains engaged in the sacred services of removing the previous day's floral offerings, the Suprabhata awakening, Thomala (garland) seva, and the intimate Ekanta seva."

Friday is especially sacred at Tirumala because the famous Abhishekam to the Moola Murti is performed on this day. It is regarded as a day of exceptional beauty and loving service to the Lord.

Saturday (Śanivāsara)

The traditional concluding line is commonly given as:

Śanivāsare Sarvābhīṣṭa Vara Pradāna Priyakaram

"On Saturday, He delights in granting the cherished wishes and blessings of His devotees."

Another traditional interpretation is:

Śanivāsare Sarva Bhakta Rakṣaṇa Priyakaram

"On Saturday, He delights in protecting all His devotees."

Saturday is closely associated with Shani. Devotees believe that sincere worship of Lord Venkateswara on this day helps them endure difficulties, reduce the effects of adverse karma, and receive the strength to face life's trials. Rather than removing every challenge instantly, the Lord grants patience, courage, and ultimately His grace.

Taken together, these seven descriptions beautifully portray the Lord as accepting every form of devotion—poetry, sacred bathing, fragrant worship, wisdom, darśana, loving temple service, and compassionate protection—throughout the entire week.

CERN NATARAJA.

 

At the entrance of CERN, the world's largest particle physics laboratory in Geneva, stands a two-metre bronze statue of Nataraja  Lord Shiva performing the cosmic dance. 

The statue was gifted by India in 2004 and remains one of the most striking symbols at the institution that discovered the Higgs boson, often called the "God particle."

Nataraja's Ananda Tandava symbolizes the eternal cycle of creation, preservation, and destruction a cosmic process that Hindu philosophy describes as the rhythm of the universe itself. 

CERN itself has explained that the cosmic dance of Shiva represents the dynamic movement of particles and energy, drawing a symbolic connection between ancient Indian philosophy and modern physics. 

The plaque accompanying the statue states that the dance unites mythology, art, and contemporary science.

It is important to note that ancient Indian scholars did not discover quantum mechanics or particle physics in the modern scientific sense. The equations, experiments, and discoveries of modern physics emerged through centuries of scientific research.

However, many observers find it remarkable that philosophical ideas expressed through Indian spiritual traditions and symbolism resonate with concepts that modern science explores today particularly the continuous cycles of creation and destruction in the universe. 

The Nataraja statue at CERN stands not as proof of ancient physics, but as a powerful reminder that humanity has long sought to understand the nature of existence through both science and philosophy. 

The CERN campus in Geneva has a bronze statue of Nataraja. It was presented as a gift by the Government of India in 2004 to commemorate India's long scientific association with CERN, which dates back to the 1960s. The statue stands on the CERN grounds between its main buildings and has become one of the laboratory's best-known landmarks. 

The symbolism is deeply philosophical. In Hindu thought, Nataraja's Ānanda Tāṇḍava (Dance of Bliss) represents the eternal cycle of:

Creation (Sṛṣṭi)

Preservation (Sthiti)

Dissolution (Saṃhāra)

Concealment or illusion (Tirobhāva)

Grace and liberation (Anugraha)

Physicists at CERN often use the dance as a metaphor, not as a scientific theory. Just as Shiva's dance symbolizes the continuous rhythm of creation and destruction, particle physics studies the continual creation, interaction, and transformation of subatomic particles. The comparison is poetic and philosophical rather than a claim that ancient Hindu scriptures describe modern particle physics. 

A plaque beside the statue includes a famous quotation from physicist and science writer Fritjof Capra, who wrote that modern physics reveals a "cosmic dance" of subatomic particles, an image he compared with Shiva's cosmic dance. This quotation was chosen to explain the symbolic connection. 

For many Indians and admirers of Hindu philosophy, the statue is a beautiful recognition that ancient philosophical imagery and modern scientific inquiry can both inspire wonder about the universe, even though they operate in different domains. It stands as a cultural and artistic symbol rather than a religious endorsement or a scientific statement.

PKR

 Puraka, Kumbhaka and Rechaka.

Saguna parnayama,  when 5he breadth is inhaled the inhalation is measured by the time taken to mentally recite a well known mantra. Puraka.

So also when the inhaled breadth is suspended the time taken is measured by the time taken to recite a mantra kumbhaka.

So to when exhalation too the time taken is measured.

Traditionally, the duration of Puraka, Kumbhaka, and Rechaka was often measured not with a clock but by the mental repetition (mānasa japa) of a mantra. This served two purposes: it regulated the breath and kept the mind fixed on the Divine instead of merely counting numbers.

Commonly used mantras include:

Om (ॐ) – the simplest and most universal.

The Gayatri Mantra (mentally repeated).

The So'ham mantra ("So" during inhalation, "Ham" during exhalation), which naturally follows the sound of the breath.

A personal Guru Mantra or Ishta Devata Mantra given during initiation.

For example, an ancient beginner's ratio might be:

Puraka – mentally chant "Om" 4 times.

Kumbhaka – chant "Om" 16 times.

Rechaka – chant "Om" 8 times.

This is the well-known 1 : 4 : 2 ratio found in many classical yoga texts. Beginners, however, usually start with much gentler ratios such as 1 : 1 or 1 : 2, and only gradually increase under the guidance of a competent teacher.

From a spiritual perspective, the mantra is more important than the count. The breath becomes an offering:

During Puraka, one receives the Lord's grace.

During Kumbhaka, one dwells in His presence.

During Rechaka, one surrenders all ego and impurities to Him.

Thus, in the Indian tradition, prāṇāyāma is not merely breathing exercise; it is breath united with mantra and awareness, making it both a physical and a spiritual discipline.

For beginners.

Puraka, Kumbhaka, and Rechaka are the three fundamental stages of yogic breathing (prāṇāyāma). They are described in classical yoga texts such as the Yoga Sutras of Patanjali, the Hatha Yoga Pradipika, and the Gheranda Samhita.

Puraka (पूरक) – Inhalation

"Puraka" means "to fill."

It is the slow, steady drawing in of the breath, filling the lungs without strain.

Symbolically, it represents receiving life, divine energy (prāṇa), and fresh vitality.

Kumbhaka (कुम्भक) – Retention of the breath

"Kumbha" means "pot" or "vessel." During retention, the body is likened to a pot holding prāṇa.

There are two principal types:

Antara Kumbhaka – holding the breath after inhalation.

Bahya Kumbhaka – holding the breath after exhalation.

Advanced texts also describe Kevala Kumbhaka, a spontaneous suspension of breath that arises naturally in deep meditation.

Kumbhaka is regarded as the heart of prāṇāyāma because it steadies the mind and helps regulate the flow of prāṇa.

Rechaka (रेचक) – Exhalation

"Rechaka" means "to empty" or "to expel."

It is the slow, controlled release of the breath.

Symbolically, it represents letting go of impurities, tension, ego, and mental restlessness.

Their deeper spiritual significance

Many teachers compare these three stages to the cosmic functions:

Puraka – Creation (Sṛṣṭi), associated with receiving and beginning.

Kumbhaka – Preservation (Sthiti), associated with stillness and balance.

Rechaka – Dissolution (Laya), associated with release and transformation.

Some traditions also relate them to the sacred syllable AUM:

A (Akāra) – Puraka

U (Ukāra) – Kumbhaka

M (Makāra) – Rechaka

The silence after AUM corresponds to the stillness beyond breath.

Practical guidance

For beginners, the breath should always remain gentle and comfortable. A simple practice is:

Inhale (Puraka) for 4 counts.

Exhale (Rechaka) for 6 counts.

Breath retention (Kumbhaka) should be learned gradually under the guidance of a qualified yoga teacher, as forceful or prolonged retention can be unsafe for people with certain medical conditions.

Ultimately, the purpose of Puraka, Kumbhaka, and Rechaka is not merely to strengthen the lungs but to calm the mind, purify the subtle channels (nāḍīs), and prepare the practitioner for meditation. As the breath becomes steady, the mind also becomes steady—a principle emphasized throughout the yogic tradition.
