Eklavya built a statue of Guru Dronacharya and considering the presence of Guru, he learned archery by himself and became perfect at this art. He was the only competitor to Arjuna at that time. When Guru Dronacharya came to know about Ekalavya, he asked him to cut his ” Right Hand's Thumb as Guru Dakshina “, so that the promise that Guru made to his student Arjuna would be fulfilled.
