SB 12.7.20

padārtheṣu yathā dravyaṁ
 san-mātraṁ rūpa-nāmasu
 hy avasthāsu yutāyutam
pada-artheṣu — within material objects; yathā — just as; dravyam — the basic substance; sat-mātram — the sheer existence of things; rūpa-nāmasu — among their forms and names; bīja-ādi — beginning from the seed (ie, from the time of conception); pañcatā-antāsu — ending with death; hi — indeed; avasthāsu — throughout the various phases of bodily existence; yuta-ayutam — both conjoined and separate.
Although a material object may assume various forms and names, its essential ingredient is always present as the basis of its existence. Similarly, both conjointly and separately, the Supreme Absolute Truth is always present with the created material body throughout its phases of existence, beginning with conception and ending with death.

Moist clay can be molded into various shapes and named “waterpot,” “flowerpot” or “storage pot.” Despite the various names and forms, the essential ingredient, earth, is constantly present. Similarly, the Supreme Lord is present throughout a material body’s stages of bodily existence. The Lord is identical with material nature, being its ultimate generating source. At the same time, the unique Supreme Being exists separately, aloof in His own abode.
