Mbh 14.50.1c

Having ascended to the top of a mountain, one should not cast one's eyes on the surface of the earth.[151] Seeing a man, even though travelling on a car, afflicted and rendered insensible by pain, the man of intelligence journeys on a car as long as there is a car path.[152] The man of learning, when he sees the car path end, abandons his car for going on. Even thus proceeds the man of intelligence who is conversant with the ordinances respecting truth and Yoga (or Knowledge and Devotion). Conversant with the qualities, such a man proceeds, comprehending what is next and next.[153] As one that plunges, without a boat, into the terrible ocean, with only one's two arms, through delusion, undoubtedly wishes for destruction; while the man of wisdom, conversant with distinctions, goes into the water, with a boat equipt with oars, and soon crosses the lake without fatigue, and having crossed it attains to the other shore and casts off the boat, freed from the thought of meum. This has been already explained by the illustration of the car and the pedestrian. One who has been overwhelmed by delusion in consequence of attachment, adheres to it like a fisherman to his boat. Overcome by the idea of meum, one wanders within its narrow range. After embarking on a boat it is not possible in moving about on land. Similarly, it is not possible in moving about on water after one has mounted on a car. There are thus various actions with regard to various objects. And as action is performed in this world, so does it result to those that perform them. That which is void of smell, void of taste, and void of touch and sound, that which is meditated upon by the sages with the aid of their understanding, is said to be Pradhana. Now, Pradhana is unmanifest. A development of the unmanifest is Mahat. A development of Pradhana when it has become Mahat is Egoism. From egoism is produced the development called the great elements.
