Question: Is Heaven one of the seven higher worlds?

Sri Chinmoy: Heaven itself is one of the higher worlds. Again, Heaven has different degrees. There is Heaven number one, Heaven number two, and so on. Inside Heaven there are more than seven worlds. Inside Heaven there can be many places, many stages of evolution: high, higher, highest.
