Question: What can you do to get them unified?

Sri Chinmoy: Through prayer and meditation you can unify them. The subtle body is always ready to inspire the physical, and the causal is always inspiring and inspiring. The physical has to go through some rigorous discipline. Then only will there be perfect harmony among the physical, the subtle physical and the causal bodies.
