Physical illness can often cause problems and present difficulties in one's life, and people often spend a lot of time, money and energy to combat illness. The medical society has found that meditation can complement the medical treatment of illness. As explained by both the Great Master Padmasambhava and Eckhart Tolle, the formation of illness is the entanglement of "thoughts in mind" and physical pain. By freeing the thoughts from the physical pain, the illness will improve by itself. Observing thoughts in mind can help patients understand the rising and fading of the thoughts in their minds when feeling physical pain. This allows the patients to separate the entanglement of the mind and the physical pain, and thereby activating the power of self-healing. Thus, if patients can observe the thoughts in their minds while receiving medical treatment, it can shorten the treatment time and save medical resources.
