“Whatever we see in this universe is but an expansion of the potency of the Supreme Personality of Godhead, just as the sunshine and heat all over the universe are expansions of the sun.”
This is from the Srimad-Bhagavatam 8.17.9
[This chapter of the Srimad-Bhagavatam is entitled, “The Supreme Lord Agrees to Become Aditi’s Son.” It describes how the Supreme Personality of Godhead was pleased by the payo-vrata ceremony performed by Aditi, and how He appeared before her in full opulence. At Aditi’s request, the Lord agreed to become her son. In today’s verse, Aditi is offering her respects to Lord Vishnu.]
My Lord, You are the all-pervading universal form, the fully independent creator, maintainer and destroyer of this universe. Although You engage Your energy in matter, You are always situated in Your original form and never fall from that position, for Your knowledge is infallible and always suitable to any situation. You are never bewildered by illusion. O my Lord, let me offer my respectful obeisances unto You.
…Anyone trying to become fully Krishna conscious must know the Lord’s glories as far as they are possible to understand. Here Aditi hints at these glories.
The universe is nothing but the external potency of the Lord. This is confirmed in Bhagavad-gita (9.4): maya tatam idam sarvam. Whatever we see in this universe is but an expansion of the potency of the Supreme Personality of Godhead, just as the sunshine and heat all over the universe are expansions of the sun.
When one surrenders unto the Supreme Personality of Godhead, he surpasses the influence of the illusory energy, for the Supreme Lord, being fully wise and being situated in the heart of everyone, especially in the heart of the devotee, gives one intelligence by which one is sure never to fall into illusion.
