Thumb rules to be followed

Few Thumb rules seem to be very important to be ensured to be followed :

1. All Inhalation and Exhalation to be done with mouth shut and only through nose unless specified.
2. Respiration activity should ideally not involve stomach at all. Wherever stomach is mentioned, its mentioned only to ensure air is pulled out of stomach as well again indication that stomach should not participate in the respiration activity.
3. All kriyas are to be done slowly and in rhythmic manner and unnecessary forceful implementation to be avoided. Unless Kriyas are specifically requiring the forceful implementation 

Will be keeping a track of the observation and things felt along. This will also keep a chronological log of the duration required for every stage.
