We are not fully abhijñaḥ. We do not know. I claim, "These hairs, my hairs, my head." But I do not know how many hairs are there. So many things. The nail is coming from my body, I do not know how it is coming. I am eating foodstuff; I do not know how it is being turned into blood and other secretions, and it is being transferred through the veins, through the pipes, here and there, and so many mechanical machine. It is machine. It is going on. But this machine is not my creation. This machine is created by this material nature. This machine is manufactured in the womb of mother. According to my karma, I enter into a particular type of mother's womb, and this machine is made by the prakṛti, by the nature. Just like this flower. There is machine. The seed will fructify, and a particular type of flower from the seed will come, because the machine is like that. Just like typewriter machine you can type, but typewriter machine, you cannot go. That you have to accept the motorcar machine. This is also machine. That . . . similarly, there are different types of machine, and from that machine, this body is coming out. Bhrāmayan sarva-bhūtāni yantrārūḍhāni māyayā (BG 18.61).
Īśvaraḥ sarva-bhūtānāṁ hṛd-deśe arjuna tiṣṭhati (BG 18.61). It is said in the Bhagavad-gītā, "Kṛṣṇa is situated everyone's heart." And He's studying the inclination of the living entity, that he wants to enjoy this material world like this. So parāsya śaktir vividhaiva śrūyate (Śvetāśvatara Upaniṣad 6.8, CC Madhya 13.65, purport). He hasn't got to do anything personally. He orders the material nature, "This living entity wants to enjoy like this. Give him the . . . this machine." So you get this machine. We have got this machine. A living entity, he does not discriminate of eating; whatever he gets, he eats. So Kṛṣṇa says that, "He wants to eat everything. So give him this machine, hog's body, so that there will be no discrimination." "He wants to remain naked. All right. Give him this body for five thousand years, standing naked as tree." The life was meant for understanding Kṛṣṇa, but he is cultivating the culture of naked civilization, how to become naked. "So all right, next time you'll remain naked for many thousands of years, standing in one place as tree." This is going on. Sarvasya cāhaṁ hṛdi sanniviṣṭaḥ (BG 15.15).
So we have to understand the activities of Kṛṣṇa. He's not dull-headed, nirākāra. Why nirākāra? He is acting in so many ways, and who acts in different ways unless He's a person? This is the conclusion. Unless He's a person, how He can act in so many different ways, according to circumstances? Just like we are receiving so many letters from different centers. So unless I am a person, how can I give direction? It is not a dull stone. So Kṛṣṇa is not dull stone. Therefore we have to study Kṛṣṇa's activities. And if we can study Kṛṣṇa's activities, if we can understand Kṛṣṇa's birth and activities, janma karma me divyam (BG 4.9), immediately we become liberated.
