1. That (intellect-Brahman) was but this—Satya (gross and subtle) alone. He who knows this great, adorable, first-born (being) as the Satya-Brahman, conquers these worlds, and his (enemy) is thus conquered and becomes nonexistent—he who knows this great, adorable, first-born (being) thus, as the Satya-Brahman, for Satya is indeed Brahman.
In order to enjoin a meditation on that Brahman called Hṛdaya (intellect) as Satya, the present section is being introduced. That refers to the intellect-Brahman. The particle ‘vai’ is a reminder. That intellect-Brahman who may be recalled—is the meaning of. the first ‘Tat’ (that). He is being described in another way—is the meaning of the second ‘Tat.’ What is that way? He was but this. With this last word the third ‘Tat.’ is connected. ‘This’ refers to something in the mind that will presently be stated. Who ‘was but this’? He who has been described as the intellect-Brahman; here the third ‘Tat’ comes in. What is he? This is being specified as Satya alone—the Satya-Brahman, or Brahman that is ‘Sat’ and ‘Tyat,’ the gross and subtle elements, in other words, consisting of the five elements. He, any one, who knows this being identified with Satya—great, because of his vastness, adorable, first-born, since this Brahman was born before all other relative beings—as the Satya-Brahman, gets the following result: As the Satya-Brahman has made all these worlds a part of himself, or conquered them, so he who knows the great, adorable, first-born Brahman identified with Satya, conquers these worlds. Also his enemy—this word is understood—is thus conquered, as the worlds are by Brahman, and becomes non-existent, i.e. is conquered. Who gets this result? To answer this the text concludes: He who knows this great, adorable, first-born (being) thus—as the Satya-Brahman. Hence the result is aptly in accordance with the meditation, for Satya is indeed Brahman.
