Guru-kṛpā: Does that mean that the atom is living entity?
Prabhupāda: Eh? No. Living entity is also atom. One class of atom is matter, and one class of atom is the living entity. That is explained in the Bhagavad-gītā: bhūmir āpo 'nalo vāyuḥ khaṁ mano buddhir eva ca (BG 7.4). These are . . . This material . . ., matter, everything is combination of atom, atomic particles. Either you take earth or take water or air or fire, everything is combination of atom. That's a fact. But we know that these atoms are coming out as the energy of Kṛṣṇa. Bhinnā. Bhinnā means the quality different; not of the same quality. Apareyam: "This is inferior quality, but there is another, superior quality, jīva bhuta, and that is living entity." So two kinds of atoms are coming from Kṛṣṇa. One is the spiritual atom, and the other is the material atom. So spiritual atoms, they are many, many times greater than the material atoms. And these material atoms is this universal . . ., innumerable universes. Some of the spiritual atoms, when they want to enjoy independently, they are given the chance of enjoying this material atom. So in the material world it is combination of material and spiritual atoms. In the spiritual world, there is no material atom; everything spirit. That is three-fourth energy, and this is one-fourth energy. Paramāṇu-cayāntara-stham (BS 5.35). (break)
Guru-kṛpā: If we say that Kṛṣṇa enters even within the atom, what is His business there?
Prabhupāda: Business is to guide the rascals like you. (laughter) Do you follow or not?
Guru-kṛpā: Well, the material atoms . . .
Prabhupāda: Because Kṛṣṇa loves you so much that even you accept this material atom, He goes to help you. Therefore He is within. Because sarvasya cāhaṁ hṛdi sanniviṣṭhaḥ (BG 15.15). The living entity has a . . ., enjoying this material world. So he has got everything. He's a person. He has got his heart. So in the heart there is Kṛṣṇa. Sarvasya cāhaṁ hṛdi sanniviṣṭho. You read Bhagavad-gītā. Why? Why He has . . ., sarvasya cāhām hṛdi sanniviṣṭho? Hmm? Who will say? Why He has . . .? Your question is "Why?"
