(Sanskrit काम मनस्) Instinctive, desire-filled mind.
"Chitta is the sub-conscious mind. It has two layers. One layer for emotion and the other for passive memory. The instinctive mind is the lower nature of human beings. It is the desire-mind or Kama Manas. The spiritual mind is the higher Manas. The seat of the mind is the heart. The mind connected to the Somachakra of the lowermost portion or under-surface of the brain is termed the organ of understanding. By Manonasa or annihilation of the mind is meant the destruction or dissolution of the lower nature, desire-mind. Sankhya Buddhi or Buddhi in the light of Sankhya philosophy is will and intellect combined. Mind is microcosm. Mind is Maya. Mind occupies an intermediate state between Prakriti and Purusha, matter and Spirit." —Swami Sivananda, Yoga in Daily Life
