I really enjoyed this section. I’ve done alternate nostril breathing before, but not to the extent that you’ve described (5x’s on each side, for 5 times). Doing this has previously calmed my nerves (e.g. stage fright). Lately, I’ve been feeling consumed by frenetic and nervous energy — in my body, I feel it as tense shoulders and shallow breathing — so look forward to doing this daily in the morning.
(Also, I noticed that the videos for the “Clear your energy channels” section are no longer available.)
