Among the four devotees, Krishna says, the jnani stands apart. Why? Because the wise one is ever-united with the divine and practices single-pointed devotion. Nothing else competes for that devotee's attention. Krishna is exceedingly dear to the jnani, and the jnani is exceedingly dear to Krishna.
Notice the reciprocity. 'Priyo hi jnanino atyartham aham, sa cha mama priyah.' It flows both ways — I am dear to the wise one, and the wise one is dear to Me. Like the bond between a grandparent and a grandchild who truly understands them. It is not one-sided.
The other three devotees — the distressed, the curious, the wealth-seeker — are not lesser. But the jnani's undivided focus, the quality of seeing nothing but the divine, gives that relationship a unique depth.
