Devotee: Nārada Muni delivered the chanting, the Hare Kṛṣṇa mantra, to the Earth?
Prabhupāda: Yes.
Devotee: Was it here before he came? And what..., how long ago did he come?
Prabhupāda: That you cannot calculate. Nārada Muni is one of the sons of Brahma, so he's present since the time of creation. And many great sages and saintly devotees are all devotees of Nārada Muni. Prahlāda Maharaja is disciple of Nārada Muni, Dhruva Maharaja is the disciple of Nārada Muni, Vyāsadeva is disciple of Nārada Muni, Vālmīki is disciple of Nārada Muni. So Nārada Muni was very expert in getting disciples. He had so many disciples. Unlimited.
