We all have an inner spiritual energy called the Kundalini, which sits dormant at the base of the spine. When this energy is awakened, it rises through our spine, comes out from the crown of our head and unites with the energy of the universe. This union of two energies is called Yoga. The word Sahaja means spontaneous. So when this spontaneous union takes place within us, we go beyond the mind and experience the present moment, a place of complete silence. This present moment is meditation. Hence, meditation is not an action, but it is a state of inner peace and mental silence.
