11.22.8

एकस्मिन्नपि द‍ृश्यन्ते प्रविष्टानीतराणि च । पूर्वस्मिन् वा परस्मिन् वा तत्त्वे तत्त्वानि सर्वश: ॥ ८ ॥

ekasminn api dṛśyante praviṣṭānītarāṇi ca pūrvasmin vā parasmin vā tattve tattvāni sarvaśaḥ

praviṣṭāni

itarāṇi

ca
also
pūrvasmin
in a prior (subtle causal element, such as the dormant presence of ether within its cause, sound)
vā
either
parasmin
or in a later (produced element, such as the subtle presence of sound within its further product, air)

All subtle material elements are actually present within their gross effects; similarly, all gross elements are present within their subtle causes, since material creation takes place by progressive manifestation of elements from subtle to gross. Thus we can find all material elements within any single element.
