Our Source is Eklavya, the son of a poor hunter, an exemplary discipleship character of the epic – Mahabharata, deeply desired to study the archery from Dronacharya to save the deer in the forest that were being hunted by leopards. But the law, rules and protocol of those days did not allow Eklavya to learn archery from Drona and Drona was also forbidden to teach by the protocol of that time rules. Eklavya deeply desired to learn the advance military arts of   archery did not leave hope.  Eklavya in the presence of virtual guru Drona practiced archery, with utmost sincerity and concentration and achieved the highest degree of excellence in the field of archery even in the absence of physical guru.
