Holy Dialogue (Pravachana Vakhyalu):
Jamuary 31, 2014: Sanatana means eternal. As Krishna says in the bhagavad-gita, “na hanyate hanyamane sarire” The living entity within the body is not destroyed when the body is destroyed, because he is not eternal. So that eternality belongs to everyone. Not that the Hindus, after giving up this body, exist, and the Muslims or Christians do not exist. Everyone exists eternally. So sanatana-dharma is meant for everyone.
