So this is the topmost devotee: prepared to do anything, without any consideration. That is pure devotee. Anyābhilāṣitā-śūnyam ānukūlyena kṛṣṇānuśīlanam (Brs. 1.1.11). There should be no personal desire. That should be zero. Anyābhilāṣitā-śūnyaṁ jñāna-karmādy-anā . . . simply one should try to please Kṛṣṇa. There is no other consideration—only to satisfy Kṛṣṇa. That is pure bhakti. That is explained by Viśvanātha Cakravartī Ṭhākura:
- vyavasāyātmikā buddhir
- ekeha kuru-nandana
- bahu-śākhā hy anantāś ca
- buddhi avyavasāyinām
- (BG 2.41)
This is perfect conclusion that, "I shall execute the desire of Kṛṣṇa." But Kṛṣṇa is not physically present before me. Then how I shall know what Kṛṣṇa desires? That is not very difficult. Kṛṣṇa's representative is there, the spiritual master. If you fulfill the desire of the spiritual master, then you fulfill the desire of Kṛṣṇa. Yasya prasādād bhagavat-prasādaḥ. That is stated by Viśvanātha Cakravartī Ṭhākura. If you please your spiritual master, then you know that, "I have pleased Kṛṣṇa." Yasya prasādād bhagavat-prasādo yasyāprasādān na gatiḥ kuto 'pi: "If you displease your spiritual master, then you are nowhere. Your position is lost."
