SŪTRA 8
"HENCE THE AWAKENING FROM HIM"
Vedānta-pārijāta-saurabha
For that very reason, the soul rises from the Supreme Lord,
as declared by the scriptural passage: "Having come back from the
Existent" (Chānd 6 10.2 ²)
Vedānta-kaustubha
None but the Supreme Soul is the place where souls rest during
deep sleep "Hence," i.e. for this reason, "the awakening",
i.e. their re-attaining the place (or the condition) of waking, "from
him", i.e. from the Supreme Soul alone, fits in, in accordance with
the statement · "Having come back from the Existent, they do not
know: 'We have come back from the Existent'" (Chānd. 6.10 2).
If anyone else be the place of the soul's deep sleep, then the
text: "Having come from the Existent" (Chānd 6 10.2) will be
contradicted. The sense is that it is not possible for the soul to lie
down in one place and arise from another. Hence it is established
that Brahman is the place of deep sleep.
Here ends the section entitled "The absence of that" (2).
1 I.e. a man sleeping on a bed is at the same time sleeping on the bedstead
and within the house. As such the bed, the bedstead and the house are his
places of sleep conjointly, yet his immediate place of sleep is the bed In the
very same manner the vein, the pericardium and Brahman are the places of the
soul's deep sleep, yet Brahman is the immediate place.
