 The two Sanskrit words Santuṣṭi (सन्तुष्टि) and Sāntr̥pti / Santṛpti (सन्तृप्ति) are closely related, but there is a subtle difference.

Santuṣṭi (Contentment)

Derived from tuṣ — "to be pleased, satisfied."

It means:

Contentment

Being happy with what one has

Freedom from constant craving

A peaceful acceptance of one's circumstances

A person with santuṣṭi may still possess desires and goals, but is not disturbed by their absence.

For example:

A sage living in a simple hut, grateful for whatever food comes his way, possesses santuṣṭi.

In Yoga, Santosha (contentment) is one of the Niyamas taught by Patanjali.

Santṛpti (Fulfillment, Complete Satisfaction)

Derived from tṛp — "to be filled, satiated."

It means:

Complete fulfillment

A sense of having received enough

Inner satiation

No remaining sense of lack

For example:

After years of searching, a devotee has a direct vision of the Lord and experiences profound santṛpti.

Or:

After drinking water when extremely thirsty, one feels tṛpti.

A Simple Analogy

Imagine eating a meal.

Santuṣṭi = "Whatever food has come to me is enough; I am content."

Santṛpti = "I have eaten fully; my hunger is completely satisfied."

One refers more to the attitude of contentment, the other to the state of fulfillment.

In Spiritual Life

Many saints distinguish them this way:

Santuṣṭi is a virtue cultivated on the path.

Santṛpti is often a fruit attained on the path.

A devotee can have santuṣṭi every day by accepting God's will.

But santṛpti arises when the heart feels completely filled by God's grace, leaving no sense of incompleteness.

A beautiful way to put it is:

Santuṣṭi says, "What I have is enough."

Santṛpti says, "I am full."

The first quiets desire; the second dissolves it.
