Those who are sectarian mistake devotional service to be sectarian

Persons who, due to being initiated by another sect of religious faith, do not find devotional

service as the common platform for approaching the Supreme Personality of

Godhead, also cannot understand Krishna consciousness. We have experience

that some students come to join us, but because of being biased in some

particular type of faith, they leave our camp and become lost in the

wilderness. Actually, Krishna consciousness is not a sectarian religious

faith; it is a teaching process for understanding the Supreme Lord and

our relationship with Him. Anyone can join this movement without

prejudice, but unfortunately there are persons who feel differently. It

is better, therefore, not to instruct the science of Krishna consciousness

to such persons.
