Question: Acceptance without Understanding?
When we do not understand something we have to refer to the guru, the devotees, and the scriptures. But even if after consulting them we are still not convinced, do we have to accept or not?
Would you please explain what is the difference between blind adherence and real realization?
Answer: You Must Inquire Further
When you are not convinced, you should not blindly accept. If you are not convinced, you should inquire further from the spiritual master and the devotees as much as is necessary until you have perfect comprehension of the science of the Absolute Truth.
When one has personally experienced the truth of Krishna one's realization is real and his adherence to the practices of Krishna consciousness are based on that personal experience, not blind adherence.
