In this verse, Shree Krishna gives the simile of the flame of a lamp. In the wind, the flame flickers naturally and is impossible to control. However, in a windless place, the flame becomes as steady as a picture. Similarly, the mind is fickle by nature and very difficult to control. But when the mind of a yogi is in enthralled union with God, it becomes sheltered against the winds of desire. Such a yogi holds the mind steadily under control by the power of devotion.
