(Sanskrit मनस्) In general use, "mind." However, in Sanskrit the word manas can mean "imagination, intellect, inclination, will, excogitation, temper, understanding, intention, mind, spirit or spiritual principle, mood, perception, opinion, intelligence, breath or living soul which escapes from the body at death, desire, sense, reflection, thought, affection, conscience, invention, spirit."
Manas is derived from the root मन् man, "to think." Manas is the root of the English term "man."

"Suddha Manas or Sattvic mind (pure mind) and Asuddha (impure) Manas or the instinctive mind or desire-mind as it is called are the two kinds of mind according to Upanishadic teaching. There is the lower mind filled with passion. There is the higher mind filled with Sattva (purity). There are two minds.
