I started Nei Gong pratice (Sung Breathing and Ji Ben Qi Gong) and I felt great. Yesterday before Nei Gong practice I tried the 5 tibetan rites and felt very dizzy, tired and felt a kind of pressure on the crown chakra (feel like something is open above the top of the head, perhaps the crown chakra itself).
My first reaction was to stop the 5 tibetan rites because I think it didn't match with Nei Gong.
Furthermore I would like to understand: what might have gone wrong with the 5 tibetan rites?
And how can I neutralize the effect on my crown chakra?
