We are from a world where we existed as souls; as particles of Light.
From the Light, Consciousness, a very subtle intelligent matter emerged and 14 planes were created out of this Divine matter.
We came down to an earth in the 7th plane to experience the Creation here.
We came here two billion years ago and are stuck up here because we did not follow certain Divine Laws.
To go back, we have to clear the dense effects (Karmas) that we attracted here.
To clear these effects, the Sapta Rishis, our Special Guides, taught us Meditation.
Some souls cleared the effects and went back. Some are clearing. The others are yet to realize this.
