Thank you Shakurav,It was very helpful,I'm interesting also with Shawn's answer.
I'm practising since 5 days only (I'd received my manual level 1&2)on the 26 July.Actually I can feel a subtle change ,I'm more quiet and I'm not tired in the afternoon like before.
I do every day at 5.30PM my 8 exercices and by 7PM the setting meditation ,the small universe.
Blessings,
Patrick
