Wonderful are his deeds.

Even the utterance of his holy name

Sanctifies him who speaks and him who hears.

Katha upanishad. 1.2.15-16.

The goal which all the vedas declare, which all austerities aim at, and which men desire when they lead a life of continence, briefly it is OM.

The syllable OM is indeed Brahman. This syllable is the highest whoso ever knows this syllable obtains all that he desires.

Mandukya upanishad.

OM! The syllable is the whole world. The past the present and future …..everything is just the word OM.

Everything here is Brahman.

The thousand names of the great lord which are based on his qualities and which the sages have sung. He is the form of the universe and is all pervasive who is of the form of sacrifice. Who is the lord of the past future and present. The creator of all living beings, their suspenders and their existence, their indweller and their wellwisher the pure supreme being, the highest goal of the liberated.
