Īśvara, the Supreme Lord, is situated in everyone's heart. Therefore it is said hṛdā. Sometimes we get education, instruction from hṛdā. That hṛdā, Kṛṣṇa, sitting in everyone's heart, instructs everyone. But those who are not devotee, they cannot understand what is the dictation. They deny. But those who are devotees, they can understand that "Here is the dictation from the Lord." Buddhi-yogaṁ dadāmi tam.
So therefore to hear from the Lord which is situated within our heart, that requires a qualification, a certain stage. Just like in the Bhagavad-gītā it is said, buddhi-yogaṁ dadāmi tam: "I give instruction to them." To whom? Not all. Of course, He's giving all. But to a devotee, teṣāṁ satata-yuktānāṁ bhajatāṁ prīti-pūrvakam: (BG 10.10) "Those who are twenty-four hours, constantly engaged in My service." Satata. Satata means twenty-four hours. Teṣāṁ satata-yuktānām: engaged. Those who are engaged twenty-four hours, bhajatām. How engaged? Bhajatām: in devotional service. How devotional service can be done? Prīti-pūrvakam, in love. They must enjoy. Here is an opportunity of serving Kṛṣṇa. The more they engage in service, the more they become pleased. That is spiritual service. There is no retirement. Material service, you'll get tired, fatigued: "Oh, I have worked so much now." In the spiritual service you'll get more energy: "Let me serve more, serve more." To such devotees, the Lord, sitting in the heart, gives instruction: "Do like this," so that he'll very soon come to Him. "Do like this." And to the others? Yes, others also He gives instruction. What instruction? "You wanted to do this. Do it now. Here is opportunity. You wanted to steal. All right. Here is the opportunity. Steal." Because everyone's heart, Kṛṣṇa is there. Sarvasya cāhaṁ hṛdi sanniviṣṭo (BG 15.15). In the Fifteenth Chapter: "I am situated in everyone's heart." Mattaḥ smṛtir jñānam apohanaṁ ca: "From Me, there is remembrance, knowledge and forgetfulness." Forgetfulness is also coming from Him.
So this is going on. Therefore the ādi-puruṣa, Kṛṣṇa is ādi-puruṣa; He's a person. But because He's not a person like us, therefore ordinary person cannot understand God can be person. He thinks that "God must be a person like me." His limited knowledge, speculator, poor fund of knowledge, he thinks that "God must be like me." Therefore in some of the scriptures He's denied personality, because this rascal thinks that "God is a person like me." Therefore it is said: not person. When it is said God is not person, that means He's not a person like you. He's not a rascal like you. That is description. When it is negatively described that He's not a person, that means He's not a person like you. But He's a person, a different person. Sac-cid-ānanda vigraha. Īśvaraḥ paramaḥ kṛṣṇaḥ sac-cid-ānanda-vigrahaḥ (BS 5.1). His person is eternal. He does not die. We die. He's full of bliss. Our, this body, is not full of bliss; full of miseries. So how God can be a person like you? Therefore sometimes He is described as impersonal. Otherwise God is a person. He's a person like us, and He's the original person. Govindam ādi-puruṣam tam ahaṁ bhajāmi. So those who are in poor fund of knowledge, they can understand that the Absolute Truth is a person. Therefore we have to take lessons from Brahmā, the supreme poet, or learned person, who is the original person. And he says: govindam, govindam ādi-puruṣam. And he says, tam ahaṁ bhajāmi: "I worship."
