Devotee: Srila Prabhupada, you said that by chanting Hare Krsna maha-mantra you can go back to home, back to Godhead. So if you chant Hare Krsna maha-mantra and not follow the regulations, not reading your books, can you go back to Godhead?

Prabhupada: Begin chanting. Then everything will be all right. Begin chanting, then all other things will be adjusted.

yena tena prakarena
manah krsne nivesayet
sarve vidhi-nisedhah
syur etayor eva kinkarah

There are vidhi-nisedha, regulative principle. If you see that you are unable to follow, then chant Hare Krsna sincerely. Then you'll be able to follow the regulative principles. Automatically.
