164. Identifications with the body alone is the root that produces the misery of birth etc., of people who are attached to the unreal; therefore destroy thou this with the utmost care. When this identification caused by the mind is given up, there is no more chance for rebirth.
165. The Prana, with which we are all familiar, coupled with the five organs of action, forms the vital sheath, permeated by which the material sheath engages itself in all activities as if it were living.
166. Neither is the vital sheath the Self – because it is a modification of Vayu, and like the air it enters into and comes out of the body, and because it never knows in the least either its own weal and woe or those of others, being eternally dependent on the Self.
167. The organs of knowledge together with the mind form the mental sheath – the cause of the diversity of things such as "I" and "mine". It is powerful and endued with the faculty of creating differences of name etc., It manifests itself as permeating the preceding, i.e. the vital sheath.
168. The mental sheath is the (sacrificial) fire which, fed with the fuel of numerous desires by the five sense-organs which serve as priests, and set ablaze by the sense-objects which act as the stream of oblations, brings about this phenomenal universe.
169. There is no Ignorance (Avidya) outside the mind. The mind alone is Avidya, the cause of the bondage of transmigration. When that is destroyed, all else is destroyed, and when it is manifested, everything else is manifested.
170. In dreams, when there is no actual contact with the external world, the mind alone creates the whole universe consisting of the experiencer etc. Similarly in the waking state also; there is no difference. Therefore all this (phenomenal universe) is the projection of the mind.
171. In dreamless sleep, when the mind is reduced to its causal state, there exists nothing (for the person asleep), as is evident from universal experience. Hence man’s relative existence is simply the creation of his mind, and has no objective reality.
172. Clouds are brought in by the wind and again driven away by the same agency. Similarly, man’s bondage is caused by the mind, and Liberation too is caused by that alone.
173. It (first) creates an attachment in man for the body and all other sense-objects, and binds him through that attachment like a beast by means of ropes. Afterwards, the selfsame mind creates in the individual an utter distaste for these sense-objects as if they were poison, and frees him from the bondage.
174. Therefore the mind is the only cause that brings about man’s bondage or Liberation: when
tainted by the effects of Rajas it leads to bondage, and when pure and divested of the Rajas and Tamas elements it conduces to Liberation.
175. Attaining purity through a preponderance of discrimination and renunciation, the mind makes for Liberation. Hence the wise seeker after Liberation must first strengthen these two.
176. In the forest-tract of sense-pleasures there prowls a huge tiger called the mind. Let good people who have a longing for Liberation never go there.
177. The mind continually produces for the experiencer all sense-objects without exception, whether perceived as gross or fine, the differences of body, caste, order of life, and tribe, as well as the varieties of qualification, action, means and results.
178. Deluding the Jiva, which is unattached Pure Intelligence, and binding it by the ties of body, organs and Pranas, the mind causes it to wander, with ideas of "I" and "mine", amidst the varied enjoyment of results achieved by itself.
179. Man’s transmigration is due to the evil of superimposition, and the bondage of superimposition is created by the mind alone. It is this that causes the misery of birth etc., for the man of non-discrimination who is tainted by Rajas and Tamas.
180. Hence sages who have fathomed its secret have designated the mind as Avidya or ignorance, by which alone the universe is moved to and fro, like masses of clouds by the wind.
181. Therefore the seeker after Liberation must carefully purify the mind. When this is purified, Liberation is as easy of access as a fruit on the palm of one’s hand.
