Question: Sometimes when I am meditating I see different visual perceptions, shaking and concentric circles that seem to rise up. What are they?

Sri Chinmoy: In these visions you are entering into different worlds. These worlds are real; they are not mental hallucinations. What you need most in your life is purification of the body, mind and vital. These visions will not go away. Out of His infinite Bounty, God has shown you these worlds. But if you want real access to these worlds, you have to become pure. Especially in your outer life you have to become purity incarnate if you want to receive these visions.
