Why Do Devotees Sometimes Ask For Darshana Of Bhagavan

“I gave you the benediction that I would take birth as your son three times. The first time I was known as Prishnigarbha, born of Prishni and Sutapa, the next birth I was Upendra born of Aditi and Kashyapa, and now for the third time I am born as Krishna from you, Devaki and Vasudeva. I appeared in this Vishnu form just to convince you that I am the same Supreme Personality of Godhead again taken birth.” (Krishna, The Supreme Personality of Godhead, Vol 1, Ch 3)
