Summary:
Though vAsudeva is the incarnation of Lord Vayu, the dust beneath whose feet is applied to heads by even the greatest among demi-gods like Shiva, Brihaspati, Indra etc., he did not reveal his true nature to anyone. Acting like a normal human being he undertook the study of the Vedas by falling at the feet of a Guru.
