Bhakti alone conquers Krishna; no material qualification, only pure devotional service achieves God-realization.Listen — Srila Prabhupada Uvaca
Śrī Caitanya-caritāmṛta, Madhya-līlā 6.254 — February 2, 1968, Los Angeles 680202CC-LOS ANGELES [20:53 Minutes] Prabhupāda: vairāgya-vidyā-nija-bhakti-yogaśikṣārtham ekaḥ puruṣaḥ purāṇaḥ śrī-kṛṣṇa-caitanya-śarīra-dhārī kṛpāmbudhir yas tam ahaṁ prapadye [Cc. Madhya 6.254] [”Let me take shelter of the Supreme Personality of Godhead, Śrī Kṛṣṇa, who has descended in the form of Lord Caitanya Mahāprabhu to teach us real knowledge, His devotional service and detachment from whatever does not foster Kṛṣṇa consciousness. He has descended because He is an ocean of transcendental mercy. Let me surrender unto His lotus feet.] This verse was composed by Sārvabhauma Bhaṭṭācārya.
You know Sārvabhauma Bhaṭṭācārya? You have not heard?
Prabhupāda: Who was he? Who was Sārvabhauma Bhaṭṭācārya? Nandarāṇī: He was a great impersonalist who was converted by Lord Caitanya to Vaiṣṇavism.
Prabhupāda: Yes. And Nandarāṇī knows better than you. [laughter] [chuckles] So girls are intelligent. Yes.
Sārvabhauma Bhaṭṭācārya was a great impersonalist and a great logician. The impersonalist school, amongst them, there are very, very learned scholars. Śaṅkarācārya himself, he was unique scholar. At the age of eight years only, he studied all the Vedas. And not only he studied; he became a critical student, Śaṅkarācārya.
He was incarnation of Lord Śiva. Therefore nobody can be compared with him. So amongst the impersonalist school, there are many great logicians and high class scholars. But according to Vedic principles, God realization does not depend on material intelligence or scholarship. It is stated in the Vedas, nāyam ātmā pravacanena labhyaḥ: "You cannot realize the self simply by arguments or very scholarly speeches." No.
Nāyam ātmā pravacanena labhyo na bahunā śrutena: "Neither by studying many, many different types of Vedic literatures." Nāyam ātmā pravacanena labhyo na bahunā śrutena na medhayā: "Neither by sharp brain or memory." These are good qualifications—to be scholarly, to be a very good speaker and to have very good memorizing power. These are materially very good qualifications. But they are not qualification for realizing God. Then what is the qualification of realizing God? Yam evaiṣa vṛṇute tena labhyaḥ [Kaṭha Upaniṣad 1.2.23]: [The Supreme Lord is not attained by expert explanations, by vast intelligence, nor even by much hearing. He is attained only by one who He Himself chooses. To such a person He manifests His own form.] "God can be realized only to whom He reveals." You cannot oblige God to become manifest before you because you are very good scholar or you are a very rich man or you are very good looking or you have got very good memorizing power. No. Yam evaiṣa vṛṇute.
