Dronacharya tests the power of concentration of his students, the Pandavas.
A basin of water is placed on the ground.
Above, a clay bird is kept rotating.
The archer has to hit the bird by looking at its reflection in the water.
Drona: "O Yudhishthira, what do you see?"
Yudhishthira: "O Acharya (teacher), I see the bird to be aimed at, the tree on which it is sitting and yourself also."
Drona: "What do you see, Bhima?"
Bhima: "I see the bird, the tree, yourself, Nakula, Sahadeva, the tables and chairs, etc."
Drona: "What do you see, Nakula?"
Nakula: "I see the bird, the tree, yourself, Arjuna, Bhima, the garden, the streamlet, etc."
Drona: "What do you see, Sahadeva?"
Sahadeva: "I see the bird to be aimed at, yourself, Arjuna, Bhima, Yudhishthira, the horses, carriages, all the onlookers, several cows, etc."
Drona: "Now then, Arjuna, what do you see?"
Arjuna: "O Revered Guru! I see nothing but the bird to be aimed at."
That is concentration. Arjuna's is the power of concentration. Concentration, when developed, becomes meditation.
