Meaning
Two Sanskrit words joined: sah, meaning that, and aham, meaning I. Together they say, I am That, where That is Brahman, the one reality Vedanta insists the seeker never actually stood apart from. Yogic texts call the practice ajapa japa, unrepeated repetition, since the breath is held to sound so as it enters and ham as it leaves, without anyone saying it.
मैं वही ब्रह्म हूँ।
