Why do some people feel uncomfortable when Kundalini rises?
Pain, agony etc are felt by people who are not accustomed to such kind of energy flow and also there is the damaged subtle body due to past karma. When a nadi, Granthi or Chakra is damaged or blocked the pain becomes extremely high and unbearable. Such people should be in constant touch with the Teacher or Guru for proper guidance, this will automatically help in reducing the pain and agony.
