vyaktam vibho sthulam idam sariram
bhunkse sthito dhamani paramesthye
avyakta atma purusah puranah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
O my lord, being changelessly situated in your own abode, you expand your universal form within this cosmic manifestation, thus appearing to taste the material world. You are Brahman, the Supersoul, the oldest, the Personality of Godhead.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
It is said that the Absolute Truth appears in three features — namely, impersonal Brahman, localized Supersoul and ultimately the Supreme Personality of Godhead, Krsna. The cosmic manifestation is the gross material body of the Supreme Personality of Godhead, who enjoys the taste of the material mellows by expanding His parts and parcels, the living entities, who are qualitatively one with Him. The Supreme Personality of Godhead, however, is situated in the Vaikuntha planets, where He enjoys the spiritual mellows. Therefore the one Absolute Truth, Bhagavan, pervades all by His material cosmic manifestation, the spiritual Brahman effulgence, and His personal existence as the Supreme Lord.
