Manomay Kosha
Manomaya means composed of manas or mind. Thinking, feeling and willing. The mind along with the five sensory organs (taste (tongue),smell (nose), vision (eyes), hearing (ear), and touch (skin), is said to constitute the manomaya kosa or “mind-sheath”. It is the cause of diversity. Man’s bondage is caused by the mind, and liberation, too, is caused by that alone.
The Manomaya Kosh is the mental faculty that receives all the sensory inputs, interprets them as good or bad and desires the good. This Kosha is much more powerful than the preceding two Koshas and governs them and is, in turn, governed by the two Koshas superior to it. It is thus central to human existence.
Many modalities of treatment like aroma, music, color, placebo therapy, shamanism work in this Kosh. Homeopathic medicines in the higher potencies also influence this Kosh.
