Moksha is the ultimate thing. It is liberation from the biggest falsehood – that we are this body or the mind. Moksha is the liberation of the soul from the confines of the mind and body. We say that we have a mind, and we have a body. We are the master of our mind and body. We should devote our time living in touch with our true self, which is the soul, or whatever other name it may be called by.
Moksha brings freedom from the afflictions of the mind and body. The body is frail; it can be broken; it can get diseased. The mind is fickle and flighty; it can get anxious or fearful or angry; it can get depressed. The body is a great tool while it works; it houses us and allows us to engage in the relative world of other souls and the material things. The mind is an even more powerful tool while it works; it helps us grasp things unmanifest and subtle, through the power of thinking. The mind allows to plan, act and be happy. To be liberated does not mean discarding the body or the mind; it means not to be confined or defined by them.
A person who has achieved Moksha experiences total and eternal bliss. Such a person is not moved or agitated by anything in the relative world. Such a person is able to ‘see’ the soul in every other person and can connect with them. Such a person can communicate with their mere presence, without using any words or even raising a finger.
Moksha is achieved by (a) a deep desire for it, and (b) the right way to transcend the relative world of mind and body. I believe that everyone fundamentally desires moksha, as no one wants to suffer pain and misery. However, the strength and the depth of desire can be different for different people. I do not believe we can will a desire, i.e. the mind cannot create a desire. Desires are what they are, and they exert the most powerful force upon us. The right way to fulfill the desire of Moksha is the way of meditation. All meditations are not the same. I believe that transcendental techniques such as TM (from Maharishi Mahesh Yogi) and Vipassana (from Buddha through Mr. Goenka) are two such techniques, though there could be many more of them.
