CC Madhya 7.101
- yāre dekhe, tāre kahe,—kaha kṛṣṇa-nāma
- ei-mata ‘vaiṣṇava’ kaila saba nija-grāma
yāre dekhe—whomever he meets; tāre—to him; kahe—he says; kaha kṛṣṇa-nāma—kindly chant the Hare Kṛṣṇa mantra; ei-mata—in this way; vaiṣṇava—devotees of the Supreme Personality of Godhead; kaila—made; saba—all; nija-grāma—his own village.
Such an empowered person would request everyone and anyone—whomever he saw—to chant the holy name of Kṛṣṇa. In this way all the villagers would also become devotees of the Supreme Personality of Godhead.
In order to become an empowered preacher, one must be favored by Lord Śrī Caitanya Mahāprabhu or His devotee, the spiritual master. One must also request everyone to chant the mahā-mantra. In this way, such a person can convert others to Vaiṣṇavism, showing them how to become pure devotees of the Supreme Personality of Godhead.
