（manas）. The manas consciousness， which is the seventh of the eight consciousnesses 八识. One of its primary functions is to perceive the subjective position of the eighth consciousness 阿赖耶识 and erroneously regard it as one's own ego， thereby creating ego attachment. Its basic nature is that of thought， but there is a difference between it and the sixth consciousness. Not consciously controllable， it is said to be a mind of a realm that gives rise to contradiction of conscious decisions， and to incessant self-love. Since it can also be called the movement of the human mind which sees the limits of human variation from within， it is necessary that for their basis of existence， humans have some fundamental thing that unceasingly continues and changes， serving as the ground for the sixth consciousness. For example the Yoga^ca^rabhu^mi-/sa^stra says: 末那任持意识令分别转 是故说为意识所依［瑜伽论 T 1579.30.651c4］. This consciousness is also called the place where good and evil are eternally accumulated， and is theorized as the connecting realm between the mano-consciousness 意识 and the a^layavijn~a^na. The so-called 'origin of delusion'， it is also called the 'stained mind'， and is associated with the four defilements of self-delusion （我癡）， self-view （我见）， egotism （我慢）， and self-love （我爱）.
