"AND LIKE A PIECE OF CLOTH."
Vedānta-pārijāta-saurabha
Just as a piece of cloth is at first rolled up, and afterwards spread
out, so is the universe.
Vedānta-kaustubha
The sense is : Just as a piece of rolled up cloth, although not known
to be a piece of cloth, does not, for that reason, become non-existent,
but is indeed existent, existing in a different form, and when spread
out once more, is known to be a piece of cloth,—so, indeed, prior to
creation, the universe remains existent indeed, though not known
to be a universe, having its name and form unmanifest; and is clearly
known as the universe at the time of creation, having its name and
form manifest. Just as the drawn forth limbs of a tortoise are not
perceived, even though existent, but do not become non-existent
thereby and are known when stretched out again; and just as the
banyan tree, existent in the seed at all times indeed in a subtle form,
is manifested in a gross form, so it is the pre-existent universe alone
which originates, in accordance with the Mahā-bhārata passage:
"Just as a tortoise, having stretched out its limbs, draws them in
again, so the soul of beings, having created beings, destroys them
again" (Mahā 12.7072b-7073a 1) and the Viṣṇu-purāṇa passage
"Just as a gigantic banyan tree is contained in a small seed, so is
the entire universe in you, the seed, during (the state of) contraction
(viz dissolution)". (V.P 1 12.666–67a 2.)

"AND JUST LIKE THE VITAL-BREATH AND THE REST."
Vedānta-pārijāta-saurabha
Just as the vital-breath, having the prāṇa, apāna and the rest,
controlled by breath exercises, etc. remains in its real form; and
