Process in Kali Yuga

harer nama harer nama 
harer namaiva kevalam 
kalau nasty eva nasty eva 
nasty eva gatir anyatha [Adi 17.21] 
"In this age of Kali there is no alternative, there is no alternative, there is no alternative for spiritual progress than the holy name, the holy name, the holy name of the Lord." (Brhan−naradiya Purana) This process is not Caitanya Mahaprabhu's invention, but is advised by the sastras, the Puranas. The process for this Kali−yuga is very simple. One need only chant the Hare Krsna maha−mantra
