If I do a lot of bhastrika or kapalabhati in a day, then I'll be tense the rest of the day and sometimes start fights for no reason. What's up with that?
What system of practice do you follow? Have you read the Spinal Bastrika Pranayama lesson on this website?
quote: With comfort established for two minutes of practice, after a week or two, spinal bastrika can be taken to three minutes, and eventually to five minutes, if desired. Spinal bastrika is very powerful in longer doses, so keep that (and the delayed effect) in mind as your experience advances.
Kapalabhati and bhastrika breathing are really for the experienced yoga practitioner, stimulating inner energies in a powerful way. Would you consider yourself advanced, Rerince?
