Jayatīrtha: Philosophy means research work.
Dr. Gerson: Yes, absolutely, yes.
Prabhupāda: Research. So by searching, searching, searching, if you do not come to Kṛṣṇa, then your searching is incomplete. That is the defect. And when you come to Kṛṣṇa understanding, then it is perfect. Then your research work is complete. That is... Kṛṣṇa says in the Bhagavad-gītā, vedaiś ca sarvair aham eva vedyam (BG 15.15). Research work means... Actually, that is science, to find out the original source. Just like they are claiming, "The original source of life is chemical." That is not knowledge, imperfect knowledge. The perfect knowledge is as Kṛṣṇa says. What is that? Ahaṁ sarvasya prabhavaḥ (BG 10.8). "I am the origin of everything." So when they come to Kṛṣṇa, then he finds out the original source. So that is possible by this research worker after many, many births, not many, many years, but many, many births. And bahūnāṁ janmanām ante: (BG 7.19) "After many, many births," bahūnāṁ janmanām ante jñānavān, "one who is actually advanced in knowledge, he surrenders unto Me." Why? Vāsudevaḥ sarvam iti (BG 7.19), that "Kṛṣṇa is the original cause of everything." Sa mahātmā su-durlabhaḥ: "Such research scholar, mahātmā, is very rare." And then He describes in the next verse that what is the symptom of these mahātmās, perfect soul. Mahātmānas tu māṁ pārtha daivīṁ prakṛtim āśritāḥ: (BG 9.13) "They are no more under the control of this material nature, they are fully under the control of spiritual nature." So what is the symptom that he is under spiritual nature, not...? Bhajanty ananya-manaso: "He is simply engaged in Kṛṣṇa." Bhajanti, "engaged in service." Bhajanty ananya-manaso: "He has no other business than to serve Kṛṣṇa." That is the symptom of a mahātmā. The Bhagavad-gītā does not say, "One who has got political business, he is mahātmā," no. Mahātmā means bhajanty ananya-manaso: "Without any diversion, simply engaged in Kṛṣṇa's business. That is mahātmā." So everything is there.
