Next question is why Radha has special status among Krishn's consorts.

There are three entities God,Soul, and Nature. Out of which God and Soul have vital energy or they are vital and nature is non-vital. Soul is minute while God is all encompassing. Most important aspects of God are infinite life, infinite knowledge and infinite happiness. Infinite happiness assumes prime position among these three.

This happiness is what everyone is after and hence it is said that everyone is after God, knowingly or unknowingly.
The extract of this infinite happiness is spiritual love and the essence of spiritual love in person is Radha.

Hence it is said that devotion to Radha will automatically fetch Krishn. That is Radha and Krishn are inseparable. Thus worship of Radha and Krishna is the worship of spiritual love and spiritual happiness. Soul is in need of both. With devotion to Radha-Krishna soul seeks ever increasing spiritual love coupled with happiness of the highest order.

Radha assumes higher position than Krishn in the divine playfield but the truth is they are two bodies one supersoul literally.
