On Consciousness and Concentration

Lets say, for example, one exhales. Now, "what goes on in your mind" here is something very simple. Regardless, even this affect is extremely hard to trace. Lets say you feel a certain something in your body as you exhale, this far from guarantees that this is indeed that main mechanism of action of the exhalation. The goal, therefore, is not to trace out every piece of the exhale, wherever and whenever it may be influential, it is to find the core of the experience of exhaling and to modify it that way. How to do such a thing can only be accomplished by a) forcing oneself to take a very exhausting and/or relieving exhale and b) allowing the exhale to be perceived as an isolated event.
