Gaurāṅgera bhakta-gaṇe jane jane śakti dhare. The purport of this song is that the devotees of Lord Śrī Caitanya Mahāprabhu are very powerful, and each and every one of them can deliver the whole world. What, then, to speak of Nārada Muni? If one follows the instructions of Nārada Muni, one can be delivered from any number of sinful reactions. This is the process. One must follow the instructions of a spiritual master; then one will certainly be delivered from all sinful reactions. This is the secret of success. Yasya deve parā bhaktir yathā deve tathā gurau. If one has unflinching faith in Kṛṣṇa and the spiritual master, the result is tasyaite kathitā hy arthāḥ prakāśante mahātmanaḥ: all the conclusions of the revealed scriptures will be open to such a person. A pure devotee of Kṛṣṇa can make the same demands that Nārada Muni is making. He says, “If you follow my instructions, I shall take responsibility for your liberation.” A pure devotee like Nārada can give assurance to any sinful man because by the grace of the Lord such a devotee is empowered to deliver any sinful person if that person follows the principles set forth.
