Question: According to BG 18.61 the Supreme Lord is situated in everyone’s heart. But then according to Bramha Samhita, Paramatma is also situated within every atom. “andantarasatam paramanu chayantarastam.” Now if I say He is situated in my heart, is He not in my hand as He is already present within every atom? What does it mean when it is said that He is present within every atom.
Answer by Romapada Swami: The Lord is present within every atom in His all-pervasive localized feature. He is simultaneously seated in the region of the heart of the soul, specifically, along with the individual living entity occupying that body. In this particular form, He acts as the witness and permitter of the soul’s activities in the material world. As the soul transmigrates through various species of life, suffering and enjoying the fruits of his actions in forgetfulness of the Lord, the Lord accompanies him through all species of life in His Supersoul feature as his constant well-wishing companion.
