‘Yogo bhoga yatey‘– yoga through bhoga. Again this is not a license for bhoga, bhoga means enjoyment. What the rishis meant was while you enjoy, realize that the enjoyment is not coming from that object you enjoy but it is tapping a little bit of happiness from the inner source, the reservoir of all happiness. Gradually you become independent of all external objects, go to the root of enjoyment and begin to enjoy within; then you are free.
