In esoteric philosophy the vegetable body is of the utmost importance. Not only does it control vital bodily functions, but the chakras are, of course, the organs of the vegetable body. So this body in effect forms the portal between the physical world and the spirit world, and if the chakras are enlivened this may lead to powers of supernatural perception and influence, the ability to communicate with disembodied spirits and also healing powers.
Our spiritual, mental, emotional and physical levels of being are connected by vortices of energy known as chakras (a Sanskrit word meaning: wheels of light). It is through these chakra vortices that imbalances on one level are passed on to another. Thus when we get very emotionally stressed, the first thing that happens is that we stop thinking straight. The imbalance on the emotional level is transmitted to the mental level. This is eventually passed onto the physical level if the imbalance is not corrected and this is how stress and emotional upset causes illness and disease or dis-ease.
