Bhagavad Gita -Swami Sivananda
Chapter-6 : THE YOGA OF MEDITATION
Summary of Sixth Discourse
Sri Krishna emphasises once again that the Yogi or Sannyasin is one who has renounced the fruits of actions, not the actions themselves. The performance of actions without an eye on their fruits brings about the purification of the mind. Only a purified mind, a mind free from desires, can engage itself in constant meditation on the Atman. Desire gives rise to imagination or Sankalpa, which drives the soul into the field of action. Therefore, none can realise permanent freedom and tranquillity of mind without renouncing desires.
The lower self must be controlled by the higher Self. All the lower impulses of the body, mind and senses must be controlled by the power of the higher Self. Then the higher Self becomes one’s friend. He who has perfect control of the body, mind and senses and is united with God, sees God in all objects and beings. He sees inwardly that there is no difference between gold and stone, between friends and enemies, between the righteous and the unrighteous. He is perfectly harmonised.
Sri Krishna proceeds to give various practical hints as to the practice of meditation. The aspirant should select a secluded spot where there is no likelihood of disturbance. He should arrange his meditation seat properly and sit in a comfortable posture, with the head, neck and spine erect but not tensed. He should fix his purified mind on the Atman by concentrating between the eyebrows or on the tip of the nose.
