The stages or eight limbs of Yoga – Dhyana
The state that arises due to uninterrupted flow of concentration is known as Dhyana or meditation.
Meditation means focusing the mind on one point, stilling the mind, in order to perceive the self. By stopping the waves of thoughts one comes to understand his true nature and discover the wisdom and tranquility that lies within. It is the seventh step of Patanjali Yoga. As concentrating the rays of the sun with a magnifying glass can burn an object, similarly focusing the scattered rays of thoughts makes the mind penetrating and powerful. With the continued practice of meditation one can discover a greater sense of purpose and strength of will and one’s thinking becomes clearer and more concentrated, affecting the person and all his or her actions.
