I appreciate your contribution to this awesome question which is pretty nice and interesting to partake on. The truth be told nobody who was born perfect in this world because we all make mistakes in one way or the other, so in the aspect of spiritual leaders or teacher since we know they are not perfect they still have more experience in their feed to pass across Which definitely can lead us to the right path in knowing more about spiritual situation because I believe there must be something that must be learnt when hearing from them which is a plus in our lives to boost our ideology in knowing more about spirituality.
