A devotee of Krishna does everything he can to help others succeed and remain on the path of pure devotional service that will take them back home back to Godhead.

Spiritual life is like learning to walk no matter how many times you or others fall down, you must always get up again and again and keep trying until you succeed.

This also includes doing everything we can to help others succeed and remain on the path back home back to Godhead.

When chanted the maha-mantra is a petition to God:

“O Krishna, O energy of Krishna, please engage me in Your service.”

The conclusion is we should never give up trying to help ourselves and as many living entities as possible to become Krishna Conscious no matter what one has done in the past or that others claim you are too fallen and wretched to win Lord Caitanya's special mercy in this age of Kali-yuga

The fact is, the special mercy in this rare Kali-yuga of receiving Lord Caitanya Mahaprabhu mercy is for EVERYONE

And He promises that He has come to save the MOST fallen souls.
