Wadaich Ji .
Eklavya was an ace archer who was so skilled in archery that his guru dronacharya asked him for his thumb as guru dakshina (gift given to the teacher).
Arjuna is known as a great warrior. The foundation of his career as a warrior was laid down when he was young; Arjuna learned everything that his guru
Dronacharya could teach him, attaining the status of "Maharathi" or outstanding warrior. A well known story about Arjuna exemplifies his powers of concentration"
Guru Dronacharya decided to test his students in their skill of archery. He hung a wooden bird from the branch of a tree and then summoned his students. He asked the first one to aim for the bird's eye but not shoot just yet. He then asked the student what the student could see. The student replied that he could see the garden, the tree, flowers, etc. Drona asked him to step aside and not shoot. He repeated the same process with a few other students. When it was Arjuna's turn, Arjuna told his Guru that the only thing he could see was the bird's eye. This satisfied the Guru and he allowed Arjuna to shoot the bird. The lesson here is the power of focus.
So in essence what i said was a person needs to have aim like ekalavya and focus like arjun. Hope this explains. By the way these are all characters from the epic Mahabharata.
