If there is dark place and if there is a fire place in that dark, immediately there is illumination. That is expanded. Similarly, God is situated in His own place. That is called Goloka Vrndavana. Goloka eva nivasaty akhilatma-bhutah [Bs. 5.37]. That is God. Although He is situated in His own abode, which is called Goloka Vrndavana, He has expanded throughout the creation by His energy.
