God dwells in every atom and heart as Supersoul, supplying all needs while awaiting His children's return to Krishna consciousness.Listen — Srila Prabhupada Uvaca
Prabhupāda: tṛtīya-puruṣa viṣṇu-'guṇa-avatāra' dui avatāra-bhitara gaṇanā tāìhāra [Cc Madhya 20.294] [The third expansion of Viṣṇu is Kṣīrodakaśāyī Viṣṇu, who is the incarnation of the quality of goodness. He is to be counted within both types of incarnations [puruṣa-avatāras and guṇa-avatāras]] virāṭ vyaṣṭi-jīvera teìho antaryāmī kṣīrodakaśāyī teìho-pālana-kartā, svāmī [Cc Madhya 20.295] [Kṣīrodakaśāyī Viṣṇu is the universal form of the Lord and is the Supersoul within every living entity. He is known as Kṣīrodakaśāyī because He is the Lord who lies on the ocean of milk. He is the maintainer and master of the universe.] So Garbhodakaśāyī Viṣṇu; then next Viṣṇu, the third incarnation, is Kṣīrodakaśāyī Viṣṇu.
Within this universe there is a planet near the polestar which is called Kṣīrodakaśāyī planet, and there Lord Viṣṇu in His incarnation of antaryāmi, Supersoul... He is acting as the Supersoul. And He is the universal form. When you think of universal form of the Lord, that is the manifestation of this Kṣīrodakaśāyī Viṣṇu.
And that Kṣīrodakaśāyī Viṣṇu as Paramātmā, Supersoul, is situated in everyone's heart, even within the atom. Aṇòāntara-stha-paramāṇu-cayāntara-stham [Bs 5.35]. [He is an undifferentiated entity as there is no distinction between potency and the possessor thereof. In His work of creation of millions of worlds, His potency remains inseparable. All the universes exist in Him and He is present in His fullness in every one of the atoms that are scattered throughout the universe, at one and the same time. Such is the primeval Lord whom I adore.] Paramāṇu means atom. Within the atom also. We think of God as very great, universal form, but God can take also form less than the atom. That is God's power. He is not only great, greatest, but He is the smallest.
Aṇor aṇīyān mahato mahīyān. Mahato mahīyān means greatest of the great, and aṇor aṇīyān, and smallest of the small. We cannot think how small He can become. That is His inconceivable potency.
So within this material world, He is within the atom, and He is within everyone's heart, in everywhere, all-pervading, and at the same time universal form, the biggest form. virāṭ vyaṣṭi-jīvera teìho antaryāmī kṣīrodakaśāyī teìho-pālana-kartā, svāmī [Cc Madhya 20.295] [Kṣīrodakaśāyī Viṣṇu is the universal form of the Lord and is the Supersoul within every living entity. He is known as Kṣīrodakaśāyī because He is the Lord who lies on the ocean of milk. He is the maintainer and master of the universe.] Now, He is the maintainer of... Whatever we are enjoying, it is due to His mercy.
In the Kaṭhopaniṣad, er, Māṇòūkyopaniṣad, it is stated, nityo nityānāṃ cetanaś cetanānām eko bahūnāṃ vidadhāti kāmān [Kaṭha Upaniṣad 2.2.13] [The Supreme Lord is eternal and the living beings are eternal. The Supreme Lord is cognizant and the living beings are cognizant. The difference is that the Supreme Lord is supplying all the necessities of life for the many other living entities.] Now, He is the supplier, whatever we want. So as pālana-kartā, as the maintainer, as the Supersoul, He is supplying.
He is supplying whatever you want: "All right." So we should not approach God as supplying agent. That is the lowest stage. He is supplying even to the cats and dogs. Then what is the difference between human being and the cats and dogs? Just like a small child, he is supplied all necessities by the father, but when the child is grown, he wants to serve the father.
