Five years. After five years hard work and placing the theses amongst the learned scholars, they admitted, "Yes, it is very nice research work." Now they have offered him a Ph.D. So it is tapasya. Tapasya. Without tapasya, you cannot get any credit. That is not possible. If one wants to get credit immediately, without tapasya, that is bogus. Therefore it is said tapasaḥ, and śrutasya. Śrutasya means hearing from the authorities. By attending lectures of the professors, of the scientific scholars, hearing . . . or Vedic knowledge.
So anyway, everyone is getting knowledge, perfection, by tapasya, by austerity, by learned scholarship. So here it is said that . . . that these things are required for describing Kṛṣṇa. These things are required for describing Kṛṣṇa. Not only on the theory, but actually to prove that this knowledge is there, Kṛṣṇa is full of all opulences, and . . . it is said . . . jñāna, jñāna-vairāgyayoś caiva śaṇṇāṁ bhaga itīṅganā. Eh? What is the beginning? Aiśvaryasya samagrasya vīryasya yaśasaḥ śriyaḥ (Viṣṇu Purāṇa 6.5.47). Kṛṣṇa means He's the full, opulent Personality of Godhead, with all riches, all reputation, all beauty, all knowledge. That you have to prove. Any department of knowledge, you have to prove that it . . . this knowledge is coming from Kṛṣṇa. Sarva-kāraṇa-kāraṇam.
- īśvaraḥ paramaḥ kṛṣṇaḥ
- sac-cid-ānanda-vigrahaḥ
- anādir ādir govindaḥ
- sarva-kāraṇa-kāraṇam
- (Bs. 5.1)
That is Kṛṣṇa consciousness. (aside) Let him sit down properly. That is scholarship. You make research work, but . . . in the śāstra it is said that Kṛṣṇa is the original person of this departmental knowledge. Suppose you are a lawyer. So Kṛṣṇa gives the law. This is research work. Just actually Kṛṣṇa gives. What is Kṛṣṇa gives? Sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja (BG 18.66). This is law. The first giver of law is Kṛṣṇa that, "You give up all nonsense. Surrender unto Me." This is law. Then you'll understand everything. Man-manā bhava mad-bhakto mad-yājī māṁ namaskuru (BG 18.65). Religion means the law given by Kṛṣṇa, or God. That is religion. Otherwise, it is not religion. That is cheating. Dharmaḥ projjhita-kaitavo 'tra (SB 1.1.2). This is cheating religion. If you do not follow Kṛṣṇa, that is cheating.
"Kṛṣṇa" means . . . when I say: "Kṛṣṇa," "Kṛṣṇa" means God. God is one. That is Kṛṣṇa. Others, they admit that God is one. But they do not know who is that one God. That is their defect. That is the difference between us and others. They do not know . . . just like if I say that "Have you got any father?" so he'll say: "Yes, I have got my father." "Now, who is your father?" "I do not know." That's not a very good credit. Because without father, mother, there is no existence. So everyone knows, "I have got a father." But who is my father, that I do not know. At least, in India, one who cannot say his father's name, immediately he becomes degraded.
