Sri Sri Ravi Shankar says, meditation is de-concentration. Meditation is accepting this moment – living every moment totally. However, the result of meditation is improved concentration. One can go deeper into one’s self and have rest with full awareness through a guided meditation. Meditation becomes completely effortless when it is done with the guidance of a master.
