Have we ever experienced in our lives that physical illness affects the mind and mental illness or tension often affects the body? If yes, then it means that mind is a finer body within our gross body. If mind is a body, then there must be something which makes it. Our gross body is made up of bones, flesh, nerves etc. But mind is not made up of bones, muscles etc. Mind is matter which is at a very high rate of vibration. And there must be some matter which is convertible into mind! And that is food! We understand that whatever we eat undergoes process of digestion in our body i.e. food undergoes breakdown process till it is converted into glucose, proteins etc. These end products are then stored or utilised by the cells for energy. That means the grossest part of food becomes excrement (waste), middle part is transformed into flesh and the subtlest (sattvic) part is utilised to form mind. Just like churning of curd leads to formation of butter. This explanation about transformation of mind (our finer body) form our food highlights the importance of constituents of what we eat. Therefore, our aim should be to consume sattvic food which is naturally vegetarian. Thus, nature of mind depends mainly on type of food which we eat.

As stated above, mind is matter which is at a high rate of vibration. This causes the mind to be in a state of uncontrolled thinking. Uncontrolled thinking hampers enlightenment of our intelligence which is pre-requisite to control our mind.

Uncontrolled mind is just like uncontrolled horse which can lead you to where the horse wants. One can understand the relation of senses, body, mind, intellect and soul from verse of Kathopnishad which explains: The body is like a chariot to which the senses are yoked like horses. The mind is like the reins which hold the horses (senses) in check. Intellect is the chaiorteer and the soul rides on the chariot. Road is the world of objects over which the chariot moves. If the reins are not held firmly and wisely (uncontrolled mind), the senses like vicious, unmanagiable horses, will get out of control and the chariot will not reach the ultimate goal (Moksha), but will go round and round in births and re-births.

Therefore, it recommended that one should practice Yoga and Meditation to control the mind, bring to rest its vibrating matter and ultimately achieve Moksha, which is the final goal of all spiritual subjects.
