People have three chief instruments for uplifting themselves: intelligence, mind, and senses. When the mind gets enslaved by the senses, you get entangled and bound. The same mind, when regulated by the intellect, can make one aware of one’s reality (Atma). The mental power gained from spiritual practice must be directed to turn the mind away from wrong paths. Direct your senses using the principle of intelligence (buddhi), and release them from the hold that the mind has on them. The mind (manas) is a bundle of thoughts, a complex of wants and wishes. As soon as a thought, desire or wish raises its head from the mind, the intellect (buddhi) must probe its value and validity — is it good or bad, will it help or hinder, where will it lead or end. If the mind does not submit to this probe, it will land itself in deep trouble. If the mind obeys your intelligence, your spiritual progress will be accelerated.
