1. For a person like this who sees in this way, thinks in this way, and has this knowledge, everything comes from the Self: Life, hope, memory, space, fire, water, birth and death, food, strength, knowledge in depth, meditation, the heart, resolution, the mind, speech, name, mantras, and all work—all this comes from the Self.

Word-for-word explanation:

Tasya ha vai etasya, of a person like this; evam paśyataḥ, who sees in this way; evam manvānasya, who thinks in this way; evam vijānataḥ, who has such knowledge; ātmataḥ prāṇaḥ, life [comes] from the Self; ātmataḥ āśā, hope [comes] from the Self; ātmataḥ smaraḥ, memory [comes] from the Self; ātmataḥ ākāśaḥ, space [comes] from the Self; ātmataḥ tejaḥ, fire [comes] from the Self; ātmataḥ āpaḥ, water [comes] from the Self; ātmataḥ āvirbhāva-tirobhāvau, birth and death [come] from the Self; ātmataḥ annam, food [comes] from the Self; ātmataḥ balam, strength [comes] from the Self; ātmataḥ vijñānam, knowledge in depth [comes] from the Self; ātmataḥ dhyānam, meditation [comes] from the Self; ātmataḥ cittam, the heart [comes] from the Self; ātmataḥ saṅkalpaḥ, resolution [comes] from the Self; ātmataḥ manaḥ, the mind [comes] from the Self; ātmataḥ vāk, speech [comes] from the Self; ātmataḥ nāma, name [comes] from the Self; ātmataḥ mantrāḥ, the mantras [comes] from the Self; ātmataḥ karmāṇi, all work [comes] from the Self; ātmataḥ eva idam sarvam iti, all this [comes] from the Self.

Commentary:

Just as waves rise from and fall back on the ocean, so also all these things—prāṇa, hope, memory, birth, death, happiness, unhappiness, etc.—come from the Self and go back to the Self. They are all within our own self.

Once we know the Self, the phenomenal world no longer exists for us.
