Suppose if you are put into a big room without any man coming there, so you cannot feel very comfortable for long time. You will feel lonely. You shall try to come out. Just like we have got experience, everyone has got experience, when we rise very high in the sky, but we cannot remain in that condition more than, utmost, eight to ten hours. Then we become very much restless. Although it is very high in the sky, but we cannot remain in that way. Therefore śāstra says:
- āruhya kṛcchreṇa paraṁ padaṁ tataḥ
- patanty adho 'nādṛta-yuṣmad-aṅghrayaḥ
- (SB 10.2.32)
One who does not take shelter of the lotus feet of Kṛṣṇa, he may rise up very high by austerity and penance, but he cannot remain in that position. He may give up artificially this material world, jagan mithyā, but he has to come down again to this mithyā jagat and open schools and hospitals, because he cannot remain in that impersonal way.
That is the experience. All so-called brahmavādī, they say that "We have become liberated," but not liberated. That is simply concoction, vimukta-māninaḥ. They think like that. Actually they are not liberated. Aviśuddha-buddhayaḥ. Without being liberated, when one speaks that, "I have become liberated," that means aviśuddha-buddhayaḥ: the intelligence is not clear. He does not know what is liberation. Liberation means prasanna-manasa, full of joyfulness. That is liberation. Evaṁ prasanna-manasaḥ, bhagavat-tattva . . . bhagavat-tattva-vijñānam (SB 1.2.20). Tattva means truth. You have to understand Bhagavān in truth.
So that, to understand in truth, that is a science. That is not sentiment. Vijñāna. In another place Kṛṣṇa says, to advise Brahmā, catuḥ-śloki-bhāgavata (SB 2.9.33/34/35/36), jñānam . . . in the Bhagavad-gītā also, jñānaṁ sa-vijñānam. Jñānaṁ me parama-guhyaṁ yad vijñāna-samanvitam (SB 2.9.31). The jñānaṁ me parama-guhyam, the knowledge of the Supreme Personality of Godhead, is very, very confidential. Jñānaṁ me parama-guhyaṁ yad vijñāna-samanvitam. It is not sentiment. It is full of scientific knowledge.
So when we understand the truth, the Absolute Truth, scientifically, that is called bhagavat-tattva-vijñānam. That bhagavat-tattva-vijñānam is understandable by a person who is liberated. One who is very busy, anxious with politics, sociology, humanitarianism, one who is very busy always in politics, how he can become interested or how he can understand bhagavat-tattva-vijñānam? That is not possible.
