There is no need to conduct research into the significance of the chanting of the Hare Kṛṣṇa mantra. The history of Ajāmila is sufficient proof of the power of the Lord's holy name and the exalted position of a person who chants the holy name incessantly. Therefore Śrī Caitanya Mahāprabhu advised:
- harer nāma harer nāma
- harer nāmaiva kevalam
- kalau nāsty eva nāsty eva
- nāsty eva gatir anyathā
- (CC Adi 17.21)
In this age of Kali, no one can perform all the ritualistic ceremonies for becoming liberated; that is extremely difficult. Therefore all the śāstras and all the ācāryas have recommended that in this age one chant the holy name.
