Explanation
Krishna contrasts sattvic unity with rajasic fragmentation. Rajasic knowledge recognizes difference but misses the deeper spiritual unity that connects all beings.
Read the traditional commentary
The second grade is rajasic knowledge. Here the mind perceives only prithaktva, separateness — manifold beings, each of a distinct kind, fundamentally divided from one another. It registers the surface diversity of the world but misses the unifying Reality within.
This is the ordinary mode of the active, ambitious mind, perpetually sorting the world into 'mine and not mine,' friend and rival, gain and loss. It is not false, for diversity is real, but it is incomplete and restless. Seeing only difference breeds desire and conflict; without the deeper vision of oneness, knowledge remains tinged with the agitation of rajas.
