Wisdom of today.

Śukadeva Gosvāmī continued: My dear King, the chanting of the holy name of the Lord is able to uproot even the reactions of the greatest sins. Therefore the chanting of the saṅkīrtana movement is the most auspicious activity in the entire universe. Please try to understand this so that others will take it seriously.

Chanting the holy name does not depend on initiation, pious activities or the puraścaryā regulative principles generally observed before initiation. The holy name does not wait for any of these activities. It is self-sufficient.

CC Madhya 15.110, Translation: 

"The holy name of Lord Kṛṣṇa is an attractive feature for many saintly, liberal people. It is the annihilator of all sinful reactions and is so powerful that, save for the dumb who cannot chant it, it is readily available to everyone, including the lowest type of man, the caṇḍāla. The holy name of Kṛṣṇa is the controller of the opulence of liberation, and it is identical with Kṛṣṇa. When a person simply chants the holy name with his tongue, immediate effects are produced. Chanting the holy name does not depend on initiation, pious activities or the puraścaryā regulative principles generally observed before initiation. The holy name does not wait for any of these activities. It is self-sufficient."
