Where did this originate from?

A Filipino man, Pi Villaraza, whilst living as a hermit on a deserted island, one day spontaneously found that a great force came into him & made him move and dance spontaneously without any control or intent on his part. He came to identify this force as the Great Mother or Shakti force or kundalini force.He found that he was able activate this force in others . Activating thier energy.
And in turn they could also pass this to others. Pi calls this process - inner dance -.
The innerdance is an intuitive and organic state of expanded consciousness that acts as a gateway or portal towards wholeness and a deeper understanding of who and what we are.   

As this process has grown more popular over recent years its is also known as Aliveness Kundalini Activation ( AKA )or Kundalini Activation Process ( KAP ).
