Prabhupāda: It is said in the Viṣṇu Purāṇa, just like fire remaining in one place spreads the heat and light, similarly, the soul also, being present in some part of our body—it is said in the heart—it spreads his heat and light, the consciousness. Similarly, God is also present. He spreads heat and light, and therefore we find so many varieties of manifestation. Just like . . . This example is very perfect: just like the light is here, it is localized, but it is spreading its illumination all over this room. The light is situated in one place. Similarly, God is situated in His kingdom or in His place; still, He is present everywhere. He is present within your heart. He is present even within the atom. Aṇḍāntara-stha-paramāṇu-cayāntara-sthaṁ govindam ādi-puruṣaṁ tam ahaṁ bhajāmi (Bs. 5.35). He is present in His abode, and He is present everywhere. He is present within the atom. He is present within your heart. This is called pariṇāma-vāda, or the presence of the energy of God.
Every one of us, we are also energy of God. There are three kinds of energies. He has got multi-energies—parāsya śaktir vividhaiva śrūyate (CC Madhya 13.65, purport) - but they have been summarized into three. The one energy is called spiritual energy, the other is called material energy, and the third is called marginal energy. The spiritual and material we can understand. At least we can feel when the . . . a living man and a dead man. A living man means spirit and matter combined. And a dead man means the matter is there; spirit is gone. So you can distinguish what is spirit and what is matter. So similarly, there is, as this is material world, there is another, spiritual world. We living entities, we, by nature, we are spiritual, but because we have got the potency either to live in this material world or in the spiritual world, therefore we are called marginal.
