Well, thank you very much for the lovely compliment White Feather. I too, love to read your work. I agree about the tongue; I am keeping it simple for beginners. I have several books that describe various breathing exercises, some by master yogis, and practice a few techniques myself. Although some people love to seek such wisdom, others, new to the concept, find it off-putting until they pop their toes in the water!
I have an idea though. Why don’t you write about such techniques? If the article has a title explaining itself as such, those looking for such help will read. I shall certainly do so myself :)
