"That yogī's perfect who's always thinking of Me," mayy āsakta-manaḥ. This is being taught. "Always thinking." And Bhagavad-gītā, in another place it is said, man-manā bhava mad-bhaktaḥ mad-yājī māṁ namaskuru mam evaiṣyasi (BG 9.34). Asaṁśaya. The aim of life should be, especially of the human body, that try to understand Kṛṣṇa. And as far as possible . . . Kṛṣṇa cannot be understood fully because He is unlimited, and we have got limited knowledge. But still, as far as possible, as much as possible, if we try to understand Kṛṣṇa, janma karma me divyam evaṁ yo vetti tattvataḥ (BG 4.9). Kṛṣṇa advents Himself, comes on this planet. He executes so many duties, takes part in so many occupational functions as human being, but everything is full of instruction. Therefore Kṛṣṇa says that "Don't try to understand, even that is also good superficially, but in truth." Janma karma me divyam yo jānāti tattvataḥ. Tattvataḥ means "in truth," "in fact."
So if anyone . . . janma karma divyam. Divyam means His birth is not ordinary birth. If it had been ordinary birth, then why we are still performing the Janmāṣṭamī ceremony, Kṛṣṇa's birthday ceremony? Many big, big kings came and gone. Who is performing the birthday ceremony of that king? But we perform according to Vedic system the birthday ceremony of Lord Rāmacandra. Nowadays we have imitated so many other birthday ceremony, but in the śāstra it is enjoined the birthday ceremony of the advent of God should be observed. The birthday ceremony of God is called jayantī. That is special constellation of the stars. But now the jayantī has been used for so many rascals and fools. This is not śāstric. So because Kṛṣṇa's janma and ordinary man's janma is not the same thing, therefore Kṛṣṇa says, janma karma me divyam. Divyam means transcendental, not material. Not material. It is spiritual, or transcendental, divyam. Janma karma me divyam yo jānāti tattvataḥ. Still you have to learn it in truth.
So if you learn this science, simply to understand why Kṛṣṇa advents, why Kṛṣṇa takes part in the Battlefield of Kurukṣetra or in other activities just like an human being . . . why? If you try to understand this fact . . . that can be known. They are all mentioned in the śāstra. The sādhus, they know; guru, he knows. So if you want to be learned in the science you can become, because śāstra is there, guru is there and sādhu is there. Sādhu-śāstra-guru-vākya. Then you will be able to understand what is Kṛṣṇa, why He advents, why His activities are transcendental.
