Yoga divides the functioning of the mind into four components: manas (the lower or sensory mind), buddhi (the inner witness), chitta (the bed of memory), and ahamkara
(self-identity) (Archarya, n.
The multiplicity of cosmic evolutes include the mahat or buddhi (intellect), the ahamkara
(ego principle), the manas (lower mind), the ten indriyas (five cognitive senses of sight, smell, taste, touch, and hearing and five conative senses of speech, prehension, movement, excretion, and reproduction), the five tanmatras (subtle essences) underlying the five sensory abilities, and the five bhutas (gross material elements of earth, water, fire, air and space).
In the fifth stage, the artist meditates on the vast emptiness (sunyata) to destroy his ahamkara
, the consciousness of self, which would otherwise intervene between him and the object of his meditation.
This reflection is what gives us the "I-sense" of individuality (the ahamkara
, or "I-sense"), as well as the ability to cognize the world around and within us.
Here na is correlated with gandha 'smell', vayu 'anus', and cittu 'intellect'; ma with rasa 'taste', guhya 'genitals', and buddhi 'judgment'; si with rupa 'sight', pada 'feet', and ahamkara
'egoism'; va with svara 'touch', pani 'hands', and manas 'mind'; and ya with sabda 'speech', yakki 'mouth', and jnana 'wisdom'.
In Samkhya, prana is an evolute of prakrti, having activity as its power, and the five bodily winds are the common functioning of buddhi (intellect), ahamkara
(ego), and manas (mind).
