Question: Would you say that the heart center sometimes opens for a few seconds end then closes again?

Sri Chinmoy: It is true. Sometimes it opens for a few seconds, a few minutes, or few days; then it may close again. It is like a window. You can leave a window open for a minute, for an hour or for a few days; it is up to you. When aspiration is intense and we become fully one with our soul, this centre remains all the time open. Otherwise it is open for a minute or a day and then it closes again. But when the six major centres from ajna to muladhara are fully open, then it is very rare that one centre will close.
