This is a great science, Kṛṣṇa science. If you are interested, there are books you can study and you can understand what is Kṛṣṇa. Janma karma me divyaṁ yo jānāti tattvataḥ (BG 4.9). So everyone should try to understand Kṛṣṇa in truth. But people do not try to understand.
- manuṣyāṇāṁ sahasreṣu
- kaścid yatati siddhaye
- yatatām api siddhānāṁ
- kaścin vetti māṁ tattvataḥ
- (BG 7.3)
Tattvataḥ means truth. That is very difficult, Kṛṣṇa says, that out of many millions of persons, one tries to become siddha. Siddha means perfect. Ahaṁ brahmāsmi. When one knows that, "I am not this material body. I am spirit soul. I am eternal servant of God, Kṛṣṇa," that is perfection. So this, for this perfection, out of many millions of persons, one becomes perfect. One who knows.
- brahma-bhūtaḥ prasannātmā
- na śocati na kāṅkṣati
- samaḥ sarveṣu bhūteṣu
- mad-bhaktiṁ labhate parām
- (BG 18.54)
So this is also very difficult to become brahma-bhūtaḥ. We are now jīva-bhūtaḥ manusyanam sahasresu, but people are not interested to become brahma-bhūtaḥ or devotee of Kṛṣṇa. They are interested to continue this material way of life, changing the body. They do not know. They think this body is all in all, but that is not the fact. That is the first instruction of Bhagavad-gītā, dehāntara-prāptiḥ (BG 2.13). You have to change your body, as you are already changing. These are stated there.
So yatatām api siddhānāṁ kaścin māṁ vetti tattvataḥ (BG 7.3). Even those who are siddhas . . . there are many big, big sannyāsīs, impersonalists, they cannot understand Kṛṣṇa. It is a fact. They consider Kṛṣṇa as ordinary human being. Avajānanti māṁ mūḍhāḥ (BG 9.11). So it is very difficult to understand Kṛṣṇa. But if you want to understand Kṛṣṇa, try to understand Kṛṣṇa from Kṛṣṇa, not otherwise. Then you will understand Kṛṣṇa.
