Imagine being asked to hit a tiny target that you cannot even look at directly. Above you, a golden fish is rotating. Beneath it, a pool of oil reflects its image. You must look only at that reflection, understand the fish's movement and release an arrow at exactly the right moment.
This was not an ordinary archery challenge. In popular retellings of the Mahabharata, three extraordinary figures are often connected with this level of skill: Arjuna, Karna and Krishna. But there is an important twist. The famous fish-eye challenge is primarily associated with Draupadi's swayamvara, and traditions differ on exactly who attempted it and what happened. So why were these warriors considered capable of such an almost impossible feat? The answer is not simply strength. It is about precision, concentration, training and extraordinary control over the mind.
