PURPORT

Since the Supreme Personality of Godhead is one without a second, there is no possibility that anything besides Himself can exist. He expands Himself by His energies in multiforms of self-expansions and separated expansions as well, just as fire expands itself by heat and light. Since there is no other existence besides the Lord Himself, the Lord's association with anything manifests His association with Himself. In Bhagavad-gita (9.4) the Lord says:

maya tatam idam sarvam jagadavyakta-murtina
mat-sthani sarva-bhutani na caham tesv avasthitah

"The complete manifestation of the cosmic situation is an expansion of the Lord Himself in His impersonal feature. All things are situated in Him only, yet He is not in them." That is the opulence of the Lord's attachment and detachment. He is attached to everything, yet He is detached from all.
