Soul is powerful

Swami Vivekananda says :

Behind the subtle body, lives Jiva or the individual soul of man. There are various discussions about the form and the size of this individual soul. According to some, it is very small like an atom; according to others, it is not so small as that; according to others, it is very big, and so on.

This Jiva is a part of that universal substance, and it is also eternal; without beginning it is existing, and without end it will exist. It is passing through all these forms in order to manifest its real nature which is purity. Every action that retards this manifestation is called an evil action; so with thoughts. And every action and every thought that helps the Jiva to expand, to manifest its real nature, is good. One theory that is held in common in India by the crudest dualists as well as by the most advanced non-dualists is that all the possibilities and powers of the soul are within it, and do not come from any external source. They are in the soul in potential form, and the whole work of life is simply directed towards manifesting those potentialities. (II, 348 –349)
