Śrī Śikṣāṣṭaka by Sri Caitanya Mahaprabhu
ānandāmbudhi-vardhanaṁ prati-padaṁ pūrṇāmṛtāsvādanaṁ
sarvātma-snapanaṁ paraṁ vijayate śrī-kṛṣṇa-saṅkīrtanam
Let there be all victory for the chanting of the holy name of Lord Kṛṣṇa, which can cleanse the mirror of the heart and stop the miseries of the blazing fire of material existence. That chanting is the waxing moon that spreads the white lotus of good fortune for all living entities. It is the life and soul of all education. The chanting of the holy name of Kṛṣṇa expands the blissful ocean of transcendental life. It gives a cooling effect to everyone and enables one to taste full nectar at every step.
Sri Caitanya Mahaprabhu’s purport: “By performing congregational chanting of the Hare Kṛṣṇa mantra, one can destroy the sinful condition of material existence, purify the unclean heart and awaken all varieties of devotional service. The result of chanting is that one awakens his love for Kṛṣṇa and tastes transcendental bliss. Ultimately, one attains the association of Kṛṣṇa and engages in His devotional service, as if immersing himself in a great ocean of love.” (Caitanya Caritamrita. Antya 20. 12-14)
