“The brahmana thought that there was no need to ask any material benefit from Lord Shri Krishna, but he was induced by the repeated requests of his wife. Moreover, he thought, ‘If I go there I shall be able to see the Lord personally. That will be a great opportunity, even if I don't ask any material benefit from Him.’” (Krishna, The Supreme Personality of Godhead, Vol 2, Ch 25)
