Arjuna versus Ekalavya
Many people regard Ekalavya’s guru-bhakti as that of the ideal disciple. But one special consideration must be observed.
Hiraṇyadhanura, the king of the outcastes (chaṇḍālās), had a son named Ekalavya. Desiring to study the science of projectile weaponry (astra-vidyā), the outcaste prince presented himself before Droṇācārya.
However, Droṇācārya did not agree to initiate him into the science of archery, for he was aware of Ekalavya’s very low status.
