Breath is a channel through which all the expression of the innermost life can be given. Breath is an electric current that runs between the everlasting life and the mortal frame. Those who have attained any intuition or miraculous power or any power have achieved it by the help of the breath. But the first essential thing is a pure channel for the breath, and that channel is the human body. If the channel is blocked, there is no possibility for the breath to flow freely. Air in itself is not bad, but when it touches the earth, it partakes the influence of the earth, and therefore can become polluted. So it is with the breath; breath in itself is pure, but if the channel through which it works is not right, it becomes impure.
