Radha to Shakti

When Radha reaches it's epitome, It becomes Shakti Holding the space around her and welcoming Narayan

Only then Narayan (Shiv) arrives making her Shakti from Radha (Narayani)

Radha is Longing Shakti is Orgasm

Only Shiva can teach Shakti in terms of intimacy : the kaal bhairav and types of medidation (nobody else)
