Don’t let laxity hamper the world’s most important movement

Unless one is firmly fixed in the regulative principles, one may perform mischievous acts, even if one is a member of the Krsna consciousness movement. We therefore advise our disciples to strictly follow the regulative principles; otherwise the most important movement for the upliftment of humanity will be hampered due to dissension among its members. Those who are serious about pushing forward this Krsna consciousness movement should remember this and strictly follow the regulative principles so that their minds will not be disturbed.
