Here Yama gives the practical method to be followed if one wishes to realize the Supreme. The word "speech" stands for all the senses. First, therefore, a man must control his outgoing senses by the mind. Then the mind must be brought under the control of the discriminative faculty; that is, it must be withdrawn from all sense-objects and cease to waste its energies on nonessential things. The discriminative faculty in turn must be controlled by the higher individual intelligence and this must be governed wholly by the Supreme Intelligence.

Arise! Awake! Having reached the Great Ones (illumined Teachers), gain understanding. The path is as sharp as a razor, impassable and difficult to travel, so the wise declare.
This is the eternal call of the wise: Awake from the slumber of ignorance! Arise and seek out those who know the Truth, because only those who have direct vision of Truth are capable of teaching It. Invoke their blessing with a humble spirit and seek to be instructed by them. The path is very difficult to tread. No thoughtless or lethargic person can safely travel on it. One must be strong, wakeful and persevering.

Knowing That which is soundless, touchless, formless, undecaying; also tasteless, odorless, and eternal; beginningless, endless and immutable; beyond the Unmanifested: (knowing That) man escapes from the mouth of death.
The Ruler of Death defines here the innermost essence of our being. Because of its extreme subtlety, it cannot be heard or felt or smelled or tasted like any ordinary object. It never dies. It has no beginning or end. It is unchangeable. Realizing this Supreme Reality, man escapes from death and attains everlasting life. Thus the Teacher has gradually led Nachiketas to a point where he can reveal to him the secret of death. The boy had thought that there was a place where he could stay and become immortal. But Yama shows him that immortality is a state of consciousness and is not gained so long as man clings to name and form, or to perishable objects. What dies? Form. Therefore the formful man dies; but not that which dwells within. Although inconceivably subtle, the Sages have always made an effort through similies and analogies to give some idea of this inner Self or the God within. They have described It as beyond mind and speech; too subtle for ordinary perception, but not beyond the range of purified vision.

The intelligent man, who has heard and repeated the ancient story of Nachiketas, told by the Ruler of Death, is glorified in the world of Brahman.
