When the Understanding, shorn of the attachment to the objects of the senses, is concentrated in the mind, then does one succeed in attaining to Brahma, for it is there that the mind with with the understanding withdrawn into it can possibly be destroyed.
बुद्धिः कर्मगुणैींना यदा मनसि वर्तते। तदा सम्पद्यते ब्रह्म तत्रैव प्रलयं गतम्॥
