The chakra system is one of the most important keys to understanding and developing one's non-physical abilities. Its exploration stems from the assumption and empirical observation of the fact that we have (at least) two bodies.

The physical body.
The spirit (or etheric) body.

The latter is subtle, not made of physical matter, and thus, cannot be perceived with the naked eye as far as most people are concerned. Although clairvoyance can be achieved, just as any other ability, by anyone, and allows seeing this "second body" in plain sight, as what many refer to as "the aura" - (the aura, described in the Bible too, being, in that perspective, the "Halo" of saints and angels).

Healing should also take into account the following bodies :

The mental body.
The emotional body.

The etheric body and physical body are connected through seven areas, referred to as "the chakras". Hereafter is a diagram explaining :

* Which physical glands or set of physical glands are connected to which chakras
* The names of each chakra

There are seven main chakras in the body. Some traditions recognize up to twelve, but the others are less relevant : these specific seven chakras are the ones we will use in the following tutorial series.

It is very important to understand that these two bodies are tightly interwoven, and equally important for the health and well-being of a person. The etheric body extends the physical body's capabilities, and sustains its functions. It is possible, through the etheric body, to support the physical body while performing uncommon tasks : some martial artists, in fact, use it to increase the resistance of their skin and make it immune to blades, or other weapons.

Chakras can be cluttered : clutters will inevitably influence the physical body and highly favor recurring pains, eczemas, allergies, etc. When healing such a chronic disease, one should try to first address etheric body limitations and blocks, possibly, mental and emotional body blocks too, and accompany this approach using physical therapy. Medication, often hazardous, should be applied only where it is absolutely necessary (in diabetes for example).
