Other teachers of the word (as Brahman) think otherwise. They listen to the sound of the ether within the heart while they stop the ears with the thumbs. They compare it to seven noises, like rivers, like a bell, like a brazen vessel, like the wheels of a carriage, like the croaking of frogs, like rain, and as if a man speaks in a cavern. Having passed beyond this variously apprehended sound, and having settled in the supreme, soundless (non-word), unmanifested Brahman, they become undistinguished and undistinguishable, as various flavours of the flowers are lost in the taste of honey. And thus it is said:

'Two Brahmans are to be known, the word-Brahman and the highest Brahman; he who is perfect in the word-Brahman attains the highest Brahman .'

23. And thus it has been said elsewhere: The syllable Om is what is called the word. And its end is the silent, the soundless, fearless, sorrowless, joyful, satisfied, firm, unwavering, immortal, immovable, certain (Brahman), called Vishnu. Let him worship these two, that he may obtain what is higher than everything (final deliverance). For thus it is said:

'He who is the high and the highest god , by name Om-kara, he is soundless and free from all distinctions: therefore let a man dwell on him in the crown of his head.'

24. And thus it has been said elsewhere: The body is the bow, the syllable Om is the arrow, its point is the mind. Having cut through the darkness, which consists of ignorance , it approaches that which is not covered by darkness . Then having cut through that which was covered (the personal soul), he saw Brahman, flashing like a wheel on fire, bright like the sun, vigorous, beyond all darkness, that which shines forth in yonder sun, in the moon, in the fire, in the lightning . And having seen him, he obtains immortality. And thus it has been said:

'Meditation is directed to the highest Being (Brahman) within, and (before) to the objects (body, Om, mind); thence the indistinct understanding becomes distinct.

And when the works of the mind are dissolved,

then that bliss which requires no other witness, that is Brahman (Atman), the immortal, the brilliant, that is the way, that is the (true) world.'

25. And thus it has been said elsewhere: He who has his senses hidden as in sleep, and who, while in the cavern of his senses (his body), but no longer ruled by them, sees, as in a dream, with the purest intellect, Him who is called Pranava (Om), the leader , the bright, the sleepless, free from old age, from death, and sorrow, he is himself also called Pranava, and becomes a leader, bright, sleepless, free from old age, from death, and sorrow. And thus it is said:

'Because in this manner he joins the Prana (breath), the Om, and this Universe in its manifold forms, or because they join themselves (to him), therefore this (process of meditation) is called Yoga (joining).
