Sūta said: When the mind is affected by tamas or rajas it is afflicted. The state of the mind at that time is called dejection. Dejection should be eschewed by strict detachment from the material objects. When one can discriminate between what is worthy and what is not worthy but still stubbornly clings to the unworthy, engrossed in diverse mundane affairs his mind becomes fickle then. These arc the impediments in the realization of yoga for a yogin.
