I agree with the statement. There is an ancient saying in Sanskrit, which when translated means, mind is the cause for one’s own bondage as well as liberation . Let us analyse the fact objectively rather than subjectively.We are made up of three types of bodies. The first one is physical body which others can see; the second is subtle body comprising mind, intellect, ego and chitta[the space where reflection takes place.] The third is causal body which constitutes three types of qualities called satva ,rajas and tamas which can be roughly translated as harmony, motion and inertia. The body in total is made up of twenty four constituents and these constituents are five fundamental elements[ether,air,fire,water and earth]five gross organs, [hands, limbs, organ of speech, excretory and reproductive organs] five subtle sense organs [ears ,eyes,nose tongue and skin], five objects of senses [ sound, touch,form, taste and smell], mind, intellect ego and chitta. Thus we can conclude, mind is a constituent of our subtle body.
Which is the seat of mind? Many confuse mind with brain and heart. The real seat of mind is five subtle senses. Thus mind pervades the entire body through sense organs which are extrovert and makes the finite soul experience the dualities in life.
What do we yearn for in life? It is nothing but happiness. Due to our ignorance, we think that happiness lies in external objects, and waste the entire life chasing them. We forget that we are the very embodiment of bliss.
In the chariot of body, the passenger is the soul; intellect is the charioteer; sense organs are the horses; mind is the bridle and the objects of senses are the path, these horses tread. When the bridle [mind] is firm, horses[sense organs] have no choice but to listen to the charioteer [ intellect].Then life will have a goal, and will be meaningful. Suppose the bridle is not firm, horses move recklessly and life becomes real disaster Therefore, bridle is the key to happiness.
Many achievers aim at annihilation of mind. When mind is weaned from its home that is sense organs and merged in intellect, it loses its separate entity and becomes intellect itself. Now the mind is empowered. When this happens life becomes beautiful.
To achieve this, the ancient seers prescribed Shravana or listening carefully to the preceptor, Manana or reflecting on the teaching of the preceptor, and Nididhyasana or meditating on what is taught. The practice of Astanga Yoga [eight limb yoga] of Patanjal’s would also be of great help. All the eight limbs i.e. Yama, Niyama, Asana, Pranayama,Pratyahara, Dharana, Dhyana and Samadhi must be given equal importance. Thus mind can both enslave and empower us.
