In this tutorial, we will refer to the breath of life using Taoist terminology, to describe a dual model composed of yin chi, dark, cold, female, and yang chi, warm, white or golden, and male. In general in nature, yin chi provides structure, yang chi provides impetus. Think "mother nature" and "father life", this is exactly what they are.

One tends to support (sometimes, useful) chaos, the other, to support order. They always are at balance within a healthy body. And circulate along our etheric channels, nadis, ideally, separately (they meet at several points though, including chakras, namely, the heart and sacral chakras).

There is "internal chi" circulating within the body, and external chi, circulating - everywhere else, however, external chi as it pertains to "magick" is what emanates from our own bodies and still is in a usable range.

Chi can be cast out/in using several gateways, namely : the third eye, the left hand, and the right hand. The right hand is useful to cast chi out : whether yin or yang chi, it can be sent using the right hand. 

Simply visualize a black "ball" to cast out yin chi, a white ball to cast yang chi. One easy way to test this is if you have a "weak" neon tube. While it is warming up, if you cast yin chi, it will instantly lighten up (as if it had received a negative electric charge, electricity). With a white ball, one can prevent the initial spark from igniting neon gas for some time. 

Following the flow of yang chi, the right hand will nurture (bring "energies" which support order), and the left hand will tend to destroy (absorb constructive "energies").

One can cast or absorb both types of chi with each hand respectively, but the flow we just described gave their names to two "main esoteric pathways" : the so called left hand path (satanism and similar trends), and right hand path. Both paths are incomplete. On both paths, anyone who wants to reach mastery will ultimately reach...

The Middle Path. From which we can turn darkness to light - our purpose when it comes to "chi", and life as a whole. Making a little beauty and order out of a little chaos, in all situations. Finally, it is highly discouraged to absorb yin chi (unless wanting to weaken one's body and develop all sorts of ailments).
