In the Bhagavad-gita the Lord says (Bg. 15.15), "I am situated in everyone's heart, and due to Me only one remembers, forgets and is cognizant, etc. Through all the Vedas I am to be known because I am the compiler of the Vedas, and I am the teacher of the Vedanta." Queen Kunti affirms that the Lord, although both within and without all living beings, is still invisible. The Lord is, so to speak, a puzzle for the common man.
Queen Kunti experienced personally that Lord Krsna was present before her, yet He entered within the womb of Uttara to save her embryo from the attack of Asvatthama's brahmastra. Kunti herself was puzzled whether Sri Krsna is all-pervasive or localized. In fact, He is both, but He reserves the right of not being exposed to persons who are not surrendered souls. This checking curtain is called the maya energy of the Supreme Lord, and it controls the limited vision of the rebelled soul. SB 1.8.19
