Mind is not a gross thing, visible and tangible. Its existence is nowhere seen. Its magnitude cannot be measured. It does not require a space to exist. Mind and matter are two aspects as subject and object of one and the same all-full Pure Spirit (Brahman), who is neither and yet includes both. Mind precedes matter. This is Vedantic theory. Matter precedes mind. This is scientific theory. Mind can be said to be immaterial only in the sense that it has not the characteristics of ponderable matter. It is not, however, immaterial in the sense that Brahman (Pure Spirit) as such is. Mind is the subtle form of matter and hence the prompter of the body. Mind is made up of subtle, Sattvic, Apanchikrita (non-quintuplicated), Tanmatric matter. Mind is all electricity. Mind is the power of your - Selfie. "Atma-Shakti". It is through mind that Brahman manifests himself as the differentiated universe with heterogeneous objects. According Chhandogya Upanishad, mind is formed out of the subtlest portion of food. Mind is material. Mind is subtle matter. This discrimination is made on the principle that the soul is the only source of intelligence; it is self-evident; it shines by its own light. But the organs (mind and senses) derive their principle of activity and life from the soul. By themselves, they are lifeless. Hence the soul is always a subject and never an object. Mind can be an object of t the soul and it is a cardinal principle of Vedanta that "that which is an object for a subject is non-intelligent (Jada)". Even the principle of self-consciousness (Aham Pratyak-Vishayatva) or Ahankara is non- intelligent; it does not exist by its own light. It is the object of apperception to the soul.
Every man has a mental world of his own. Every person entirely differs from another person in mode of thinking, temperament, taste, mentality, physical characteristics, etc. Physically also a man differs from another man, although there might be slight resemblance. Observe carefully the nose, the ears, the lips, the eyes, the eyebrows, the arrangement of teeth, the shoulders, hands, fingers, toes, look, voice, gait, way of talking, etc., of different men. We will find vast differences between any two persons. Even the lines of the palm will differ. No two leaves are alike. Variety is the beauty of creation. There are various types of mind. The Sadhana and path of Yoga also vary according to the type of mind, temperament and capacity. Tastes also differ. The sight of a fish brings excessive joy to a fish-eater. The sight of meat brings a peculiar joy to a meat-eater. Is this not a mystery that an object lies outside and saliva appears in the tongue at the sight of it? Because we have this experience daily in everyday life. we do not attach much importance to it. Even an infinitely superior mind is yet a mind.
