_Question:_ I feel a strange vibration in my neck. First there is joy, and then this vibration. What is that?

Sri Chinmoy: If you feel joy when you feel this vibration, then it is a good vibration. If you are getting joy, then definitely it is good. Anything that gives you joy, innocent joy, pure joy, is good. When you get a vibration which encourages you, inspires you, that means it is a good thing that is happening inside you, very good, encouraging and illumining.
