DvA suparNA and asmitA

DvA suparNA is the beginning of a verse in the MuNDaka Upanishad:

द्वा सुपर्णा सयुजा सखाया समानं वृक्षं परिषस्वजाते ।

तयोरन्य: पिप्पलं स्वाद्वत्त्यनश्नन्नन्यो अभिचाकशीति ॥

Two golden birds that are ever associated and have similar names, cling to the same tree. Of these, the one eats the fruit of divergent tastes, while the other merely looks on without eating. 

The feeling of asmitA, which is a klesha in the Yoga SUtra is puruSha entangled with guNas, which is the state of the jIvAtma. Just see the guNas playing with guNas like the other bird, paramAtma.
