A pure and pious devotee of the Lord and he who does respect living and non-living entity.equally[sama dharshan - meaning treating equally] is a pure vaishnava. A vaishnava is one who does not even think of hurting anyone by words, thoughts, and actions. It is to be noted that a vaishnava is not identified by his religious marks on his body but by his attitude and qualities. A non-hindu samadarshan may be a vaishnava.
