Everyone's heart, there is kṛṣṇa-bhakti. Otherwise, how these Europeans, Americans, Canadians, Japanese, they are taking to Kṛṣṇa consciousness? We have Muhammadans also. Many Muhammadans, they are taking to Kṛṣṇa consciousness. Therefore it is to be understood that Kṛṣṇa consciousness, or love for Kṛṣṇa, is existing in everyone's heart. It is simply to be awakened. Nothing more.
How it is awakened? Śravaṇādi-śuddha-citte karaye udaya. If you simply give your aural reception to the kṛṣṇa-kathā. Kṛṣṇa-kathā means what is spoken by Kṛṣṇa, the Bhagavad-gītā, and kṛṣṇa-kathā means speeches and words which are spoken about Kṛṣṇa. The Śrīmad-Bhāgavatam is also kṛṣṇa-kathā, and Bhagavad-gītā is also kṛṣṇa-kathā. One is directly spoken by Lord Kṛṣṇa, and one is spoken by Lord . . . I mean to say, Vyāsadeva, the great saint Vyāsadeva, about Kṛṣṇa. So Caitanya Mahāprabhu says that "You preach this kṛṣṇa-kathā to everyone, and then you become a spiritual master under My order."
So if we strictly follow these principles, if we simply say what Kṛṣṇa says, what Kṛṣṇa desires . . . Kṛṣṇa says: sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja (BG 18.66). If you cannot do anything, simply speak to your friend, "My dear friend, please surrender unto Kṛṣṇa." You surrender first of all yourself and speak to others, "Please surrender unto Kṛṣṇa." Your life becomes sublime and successful.
