Manas

Manas (devanāgarī: मनस्) is the Sanskrit word for "mind", from the root man, "to think". In Hinduism it is the recording faculty that receives impressions gathered by the sense from the outside world, coordinating sensory impressions before they are presented to the higher faculty of buddhi (the "intellect" in Hinduism). Manas is one of the four parts of the antahkarana (the "internal organ"), the other three parts being buddhi (the intellect), citta (the memory) and ahamkāra (the ego).

In Theosophy manas is the fifth principle in human beings. It was defined by H. P. Blavatsky as follows:

Manas (Sk.). Lit., “the mind”, the mental faculty which makes of man an intelligent and moral being, and distinguishes him from the mere animal; a synonym of Mahat. Esoterically, however, it means, when unqualified, the Higher EGO, or the sentient reincarnating Principle in man. When qualified it is called by Theosophists Buddhi-Manas or the Spiritual Soul in contradistinction to its human reflection—Kâma-Manas.
