A cell is a mass of protoplasm with a nucleus. It is endowed with intelligence. Some cells secrete, while some cells excrete. The cells of the testes secrete semen; the cells of the kidneys excrete urine. Some cells act the part of a soldier. They defend the body from the inroads or attacks of foreign poisonous matter and germs. They digest and throw them out. Some cells carry food materials to the tissues and organs. The cells perform their work without your conscious volition. Their activities are controlled by the sympathetic nervous system. They are in direct communion with the mind in the brain. Every impulse of the mind, every thought, is conveyed to the cells. They are greatly influenced by the varying conditions or states of the mind. If there are confusion, depression and other negative emotions and thoughts in the mind, they are telegraphically transmitted through the nerves to every cell in the body. The soldier-cells become panic-stricken. They are weakened. They are not able to perform their function properly.
Lots of people battling with physical ailments are sick not because of diseases but because they nurture unwholesome thoughts.
Pay attention to your thoughts!
