असंशयं महाबाहो मनो दुर्निग्रहं चलं।
अभ्यासेन तु कौन्तेय वैराग्येण च गृह्यते।।6.35।।
6.35 The Blessed Lord said O mighty-armed one, undoubtedly the mind is untractable and restless. But, O son of Kunti, it is brought under control through practice and detachment.
6.35 The Lord said No doubt, the mind is hard to subdue on account of its fickle nature. However, it can be subdued with difficulty by cultivating favourable attitude in the direction of the self by repeated contemplation of Its being a mind of auspicious attributes (these being eternality, self-luminosity, bliss, freedom from Karma, purity etc.), and by the absence of hankering produced by seeing the host of evil alities in objects other than the self hankered for.
