Chanting Hare Krsna

Caitanya Mahāprabhu while passing on the road, He used to chant:

kṛṣṇa kṛṣṇa kṛṣṇa kṛṣṇa kṛṣṇa kṛṣṇa kṛṣṇa he
kṛṣṇa kṛṣṇa kṛṣṇa kṛṣṇa kṛṣṇa kṛṣṇa kṛṣṇa he
kṛṣṇa kṛṣṇa kṛṣṇa kṛṣṇa kṛṣṇa kṛṣṇa rakṣa mām
kṛṣṇa kṛṣṇa kṛṣṇa kṛṣṇa kṛṣṇa kṛṣṇa pāhi mām
rāma rāghava rāma rāghava rāma rāghava rakṣa mām
kṛṣṇa keśava kṛṣṇa keśava kṛṣṇa keśava pāhi mām

“O Lord Kṛṣṇa, please protect Me and maintain Me. O Lord Rāma, descendant of King Raghu, please protect Me. O Kṛṣṇa, O Keśava, killer of the Keśī demon, please maintain Me.”

If one always chants the holy name of Kṛṣṇa, gradually one is freed from all reactions of sinful life, provided he chants offenselessly and does not commit more sinful activities on the strength of chanting the Hare Kṛṣṇa mantra. In this way one is purified, and his devotional service causes the arousal of his dormant love of God. If one simply chants the Hare Kṛṣṇa mantra and does not commit sinful activities and offenses, one’s life is purified, and thus one comes to the fifth stage of perfection, or engagement in the loving service of the Lord (premā pum-artho mahān).

Note this verse is also recited before reading Kṛṣṇa Book
