Caitanya Mahaprabhu has recommended that everyone chant the Hare Krishna mantra just to cleanse the dust from the heart. If the dust of the heart is cleansed away, then one can actually understand the importance of the holy name.
Nectar of Devotion, Chapter 12,
Krishna is present fully in His holy name and this is realized by the humility and sincerity in our chanting.
Chaitanya Mahaprabhu has recommended that everyone should chant the Hare Krishna mantra just to cleanse the dust from the heart. If the dust of the heart is cleansed away, then one can actually understand the importance of the holy name.
It is the aspiration of a devotee that while he chants the Hare Krsna maha-mantra his eyes will fill with tears, his voice falter and his heart throb. These are good signs in chanting the holy name of the Lord.
Purport on Chaitanya Caritamrta Adi Lila 7.81
The wild tigers, elephants, bear and deer all together accompanied the Lord, and the Lord accompanied them in sankirtana. By this He proved that by the propagation of the sankirtana movement (congregational chanting and glorifying of the name of the Lord) even the wild animals can live in peace and friendship, and what to speak of men who are supposed to be civilized.
