There are innumerable planets and innumerable living entities upon those planets in the air and in the water. There are millions and trillions of living entities everywhere, and they are engaged by māyā in suffering and enjoying the results of their fruitive activity life after life. This is the position of the materially conditioned living entities. Out of many of these living entities, if one is actually fortunate (bhāgyavān), he comes in contact with a bona fide spiritual master by Kṛṣṇa’s mercy.
How one can become this fortunate can be seen in the life of Śrīla Nārada Muni. In his previous life, he was born of a maidservant. Although he was not born into a prestigious position, his mother was fortunately engaged in rendering service to some Vaiṣṇavas. When these Vaiṣṇavas were resting during the Cāturmāsya period, the boy Nārada took the opportunity to engage in their service. Taking compassion upon the boy, the Vaiṣṇavas offered him the remnants of their food.
By serving them and obeying their orders, the boy became the object of sympathy for the Vaiṣṇavas, and, by the Vaiṣṇavas’ unknown mercy, he gradually became a pure devotee. In the next life he was Nārada Muni, the most exalted of Vaiṣṇavas and the most important guru and ācārya of Vaiṣṇavas.
Following in the footsteps of Nārada Muni, the Kṛṣṇa consciousness movement is rendering service to humanity by giving everyone a chance to come in contact with Kṛṣṇa. If one is fortunate, he becomes intimately related with this movement. Then, by the grace of Kṛṣṇa, one’s life becomes successful. Everyone has dormant kṛṣṇa-bhakti-love for Kṛṣṇa and in the association of good devotees, that love is revealed.
Dormant devotional service to Kṛṣṇa is within everyone. Simply by associating with devotees, hearing their good instructions and chanting the Hare Kṛṣṇa mantra, dormant love for Kṛṣṇa is awakened. In this way one acquires the seed of devotional service.
