A cart can move only when two bullocks are yoked to it. And the cart can move safely only when the bullocks are trained to pull carts and when they are used to the road on which they have to walk. Instead, if they are ignorant of the process of pulling carts, if they have not walked on the road, if they have never stepped out of their shed, or if they have always moved only round and round the post to which they have been tied, the journey cannot proceed! So also, the cart of inner consciousness (Anthah-karana) cannot move by itself; it must be attached to the bullocks of intelligence (Buddhi) and mind (Manas), and made to follow their tracks. But, prior to the journey, the bullocks - intelligence and mind - should be conversant with the road to the village that the inner consciousness (Anthah-karana) is eager to reach. They must be trained to proceed in that direction. If this is done, the journey will be easy and safe.
