Many people think the mind can be controlled. That is not a useful idea. Like the monkey, the mind can never actually be controlled; it can only be directed. If you want to try to control your mind, you will regret the results. Forget the word "control" and learn to direct your mind and energy on all levels.
Every human being has potentials for healing. The healing energy is flowing without any interruption in every human heart. By the right use of the dynamic will, these channels of healing energy can be directed to the suffering part of the body and mind. The healing energy can nourish and strengthen the sufferer. The key to healing is selflessness, love, dynamic will, and undivided devotion to the Lord within.
The word guru is a compound of two words, gu and ru. Gu means darkness and ru means light. That which dispels the darkness of ignorance is called guru. The energy and action of removing darkness are guru. Guru is not a person, it is a force driven by grace.
