Mind is restless, unsettled, confused, indecisive and uncontrollable. Mind jumps from one thought to another just like a monkey who jumps from one tree to another. The monkey like mind is not satisfied in the present moment. It is constantly distracted with replaying the happenings of past events or planning for the future. Focusing of mind to stay in present can be achieved by practicing meditation.
Meditation is a technique for having full control over mind by constant observation of thoughts entering the mind. It trains mind to work without getting tensed, stressed, tired and aged. It keeps the mind cheerful, peaceful, calm, serene and young as there is increase of grey matter. Most importantly it helps one to be peaceful in turbulent times.
