Don't waste your time for acquiring so-called mystic power. Just devote yourself to remain a pure devotee of Kṛṣṇa, and you become the supreme mystic. That is confirmed in the Bhagavad-gītā:
- yoginām api sarveṣāṁ
- mad-gatenāntarātmanā
- śraddhāvān bhajate yo māṁ
- sa me yuktatamo mataḥ
- (BG 6.47)
There are many yogīs, mystics, but Kṛṣṇa confirms that "Of all the yogīs, of all the mystic, a person who is always thinking of Me," śraddhāvān bhajate yo mām, yoginām api sarveṣāṁ mad-gatenāntarātmanā, "always thinking Me, Kṛṣṇa, within himself:
- Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare
- Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare."
So Kṛṣṇa said, "he is the best yogī." Yoginām api sarveṣāṁ. Sarveṣam means "of all." "Of all kinds of yogīs, the best yogī is who is always thinking of Me."
That is Kṛṣṇa's philosophy. He is teaching in the Bhagavad-gītā, man-manā bhava mad-bhakto mad-yājī māṁ namaskuru (BG 18.65). Four things. If you sincerely do these four things—always think of Kṛṣṇa, man-manā; just become His devotee, man-manā bhava mad-bhakto; mad-yājī, worship Kṛṣṇa . . . just like we do in the temple room. Man-manā . . . you can do worship anywhere if you are a devotee. A devotee can worship Kṛṣṇa anywhere, underneath a tree, because Kṛṣṇa is in everyone's heart, īśvaraḥ sarva-bhūtānāṁ hṛd-deśe 'rjuna tiṣṭhati (BG 18.61). So if underneath a tree you think of Kṛṣṇa and chant Hare Kṛṣṇa, that is sufficient. Kṛṣṇa does not require any big paraphernalia. He only wants how you are a sincere devotee. That's all. And that devotional service can be discharged in any condition. Ahaituky apratihatā (SB 1.2.6). It cannot be checked by the material circumstances. This is the process of Kṛṣṇa consciousness.
And you see the five-years-old boy, how he was protected from all kinds of dangers, and he refused to take any benediction. He refused. The devotee should not be a mercantile man: "If You give me something, then I shall give You something." That is business. A devotee is not like that. He understands that he is eternal servant of Kṛṣṇa, his duty is to serve Kṛṣṇa.
