know vedanta

He who had made soul  not comprehend him: from him who saw him surely is he hidden.
He, yet enveloped in his mother's bosom, source of much life, had sunk into void. They call him Indra, mitra, varuṇa, agni, and he is heavenly nobly winged as twin bird in every heart.To what is one, sages give many a title they call it agni, yama, indra .

that which has to be known, knowing which one attains to immortality, the

beginningless supreme Brahman, called neither being nor non-being.

 With hands and feet everywhere, with eyes, heads and mouths everywhere, with ears

everywhere, He exists in the worlds, enveloping all.

 Shining by the functions of all the senses, yet without the senses; unattached, yet

supporting all; devoid of qualities, yet their experiencer,

 Without and within (all) beings, the unmoving and also the moving; because of his

subtlety, unknowable; and near and far away is that.

 And undivided, yet he exists as if divided in beings; He is to be known as the supporter

of beings; He devours and he generates also. The soul seated in nature experiences the qualities born of nature; attachment to the qualities is the cause of his birth in good and evil wombs.

 The Supreme soul in this body is also called the spectator, the permitter, the supporter,

the enjoyer, the great Lord and the Supreme Self. When a man sees the whole variety of beings as resting in the One, and spreading forth from that alone, he then becomes Brahman. A man attains to unity with the Supreme when he knows or realises through intuition that all these manifold forms are rooted in the One. Like waves in water, like rays in the sun, so also all forms are rooted in the One.

 Being without beginning and devoid of (any) qualities, the Supreme Self, imperishable,

though dwelling in the body  neither acts nor is tainted! Therefore, with the utterance of “Om” are the acts of gift, sacrifice and austerity as enjoined in the scriptures always begun by the students of Brahman.

 Uttering Tat, without aiming at the fruits, are the acts of sacrifice and austerity and the

various acts of gift performed by the seekers of liberation.

 The word Sat is used in the sense of reality and of goodness; and so also it is used in the sense of an auspicious act!

 Steadfastness in sacrifice, austerity and gift, is also called Sat, and also action in

connection with these (or for the sake of the Supreme) is called Sat.

 Whatever is abandoned, given or performed, and whatever austerity is practised without

faith, it is called Asat. It is naught here or hereafter (after death).

Whatever abandonment , austerity or charity done without being dedicated

to the Lord will be of no avail to the doer in this earthly life here or in the life beyond hereafter.
