It is an unquestionable truth of life that the most precious possession that you have is your very own spiritual self. As we tend to move away from that intrinsic part of ourselves the body gets trapped by negative energies, which are the root cause of ailments. Spiritual therapies channelise your energies back on the right track, by venturing deep within yourself.
As God's children, all individuals have a part of divinity in themselves. By invoking the strength of that divinity through the control over ones thoughts, one can shape ones life very strongly. It is therefore important that one should attempt to root out all negative thoughts from the mind and concentrate on only the positive ones.
The negative thought patterns which cause ailments are anger, criticism, resentment and guilt. It is utterly impossible to maintain a healthy body under such distressed condition. For instance, criticism indulged in over long periods will often lead to disease as arthritis. Anger turns into things that boil and burn and in the long run infect the body and it also leads to heart ailments. Resentment eats into your system and ultimately leads to tumour and cancer. Guilt always seeks punishment and leads to all sorts of pain.
Next to hate, worry is just about the worst form of self-destructive mental activity. Hatred is the most severely damaging mental activity. It poisons the body and the mind and its effects are almost permanent. Similarly if you have no will to live, you are unlikely to have a long life. On the other hand, if you intend to live with a positive mind, you will definitely live a long and healthy life. Thus a person who exercises, meditates and thinks positively, is telling his body that he wants to stay healthy throughout his life.
Think of the experiences in life that you wish to be fulfilled. And you will find your thought patterns taking real shapes. This phenomenon is called metaphysical causation. This describes the power in the words and thoughts to create experiences. And explains the connection between thoughts and your physical self. Thus a stiff neck could easily be indicative of inflexibility in a person to listen to the other side of an argument.
So if need be, be willing to change your words and thoughts and watch your life change right before you. The way to control your life is to control your choice of words and thoughts. Since no one can delve into the depths of your, but you. Although easier said than done, this can be achieved better by practicing the arts of relaxation and concentration. For which one can in turn take the help of music and mantras.
