What is salvation and why is it necessary?
When we feel nature and material things through the senses and interpret that experience through the experiences of our brain, we experience happiness or unhappiness. The more we detach the senses from nature, the more we will be far away from this feeling of happiness and sorrow because the senses are the producers and carriers of feelings like happiness and sorrow. But this cannot happen suddenly. This requires continuous practice. The practice of engaging the senses with their objects is to be done until the senses become independent of the external nature.
Until this exercise is completed, complete caution is necessary. At the same time it is essential to remember the irreversible principle of change. It has to be remembered that everything that emanates from nature, everything that is material is constantly changing. It cannot live without changing. And these changes eventually lead to a change in appearance. All this is so natural that there is no reason to be happy or sad over it. What has to be changed has to be changed.
Now let's see whether the person who achieves this status is like a stone. No. If that person becomes like a stone, then cannot even know what his/her actual reaction should be. In fact, such a person is patient. Actually he knows what he has to do. He/she knows how to take change naturally and how to detach his/her senses from nature. When we practice and assimilate the immutable principle of this change, then our senses become free from the external world, uninfluenced by external nature and can give neither pleasure nor pain. This is the stage when one becomes free from nature. One can be free from nature only in one's lifetime. One's liberation from nature is called salvation. Such a person does not determine himself or herself as per the outside world. In this situation his/her ego which is made up of his/her body, senses/feeling and intellect disappears, and attains moksha i.e. liberation.
When we are absolutely alone, in society, in business, or in any other state, due to the combination of our senses with nature, we get pleasure and pain, due to which we get extra stress Due to this our life becomes meaningless. We have to reach somewhere and we reach somewhere. It is possible to deviate from the path only because we all find the external nature and connect our ego with it.
Detachment from this bondage is salvation. The basis of Nishkaam Karma is the absence of attachment and when we get the feeling of absence of attachment, we are in the state of salvation. The word salvation seems heavy to the people and it seems that it is found only after the end of life. Moksha i.e. Salvation is not an attainable thing after death, rather it is a state of living a life in which a person has become accustomed to fulfill his obligations by giving up attachment.
