In the evolution of the Origin into multiplicity, the very first thing that happens is the icchA (Wish, Desire) and the Love-pair. So also, at the very end of the sAdhanA for the involution of the jIva into the Source, the nADI goes through the nAyikA stage just before the last stage of the Union with the Supreme.
That is the stage of identity with Shakti. That is when there is an anguish for union with the nAyaka, that is, ShivaM. It is in that anguish one surrenders totally with the attitude: ‘ I am incapable of doing anything. It is all Your Wish’.
