SB 8.12.5
ady-antav asya yan madhyam
idam anyad aham bahih
yato ’vyayasya naitani
tat satyam brahma cid bhavan
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The manifest, the unmanifest, false ego and the beginning, maintenance and annihilation of this cosmic manifestation all come from You, the Supreme Personality of Godhead. But because You are the Absolute Truth, the supreme absolute spirit soul, the Supreme Brahman, such changes as birth, death and sustenance do not exist in You.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
According to the Vedic mantras, yato va imani bhutani jayante: everything is an emanation of the Supreme Personality of Godhead. As stated by the Lord Himself in Bhagavad-gita (7.4):
bhumir apo ’nalo vayuh
kham mano buddhir eva ca
ahankara itiyam me
bhinna prakrtir astadha
“Earth, water, fire, air, ether, mind, intelligence and false ego — all together these eight comprise My separated material energies.” In other words, the ingredients of the cosmic manifestation also consist of the energy of the Supreme Personality of Godhead. This does not mean, however, that because the ingredients come from Him, He is no longer complete. Purnasya purnam adaya purnam evavasisyate: “Because He is the complete whole, even though so many complete units emanate from Him, He remains the complete balance.” Thus the Lord is called avyaya, inexhaustible. Unless we accept the Absolute Truth as acintya-bhedabheda, simultaneously one and different, we cannot have a clear conception of the Absolute Truth. The Lord is the root of everything. Aham adir hi devanam: He is the original cause of all the devas, or demigods. Aham sarvasya prabhavah: everything emanates from Him. In all cases — nominative, objective, positive, negative and so on — whatever we may conceive of in this entire cosmic manifestation is in fact the Supreme Lord. For Him there are no such distinctions as “this is mine, and this belongs to someone else,” because He is everything. He is therefore called avyaya — changeless and inexhaustible. Because the Supreme Lord is avyaya, He is the Absolute Truth, the fully spiritual Supreme Brahman.
