The ego by its nature directs the mind and attention downwards and outwards. Thus we experience more the sensory objects and the bodily and vital-emotional sensations.
Because of this extroversion of mind we fail to realize what happens in our psyche and mind and we cannot become aware of our divine essence and realize that we are not a body-mind entity but a soul that is embodied in a physical body.
Therefore in order to to realize what we really Are, we have to direct the mind and attention inwards and upwards. We are inside when we gather the attention from the senses and focus it in the mind itself and up when we overcome the mind and focus the attention on what is more subtle and beyond the mind, the eternal soul!
The greatest obstacle in this process is the ego itself which does not want to leave the objects and the sensory experiences. So far it resists with various ways our effort to direct the mind and attention within, in our center of existence where there is only silence and total lack of objects and sensorial experiences.
He who achieves to conquer his mind and senses and eliminate the egoic tendencies and desires by systematic, sincere and incessant practice and by constant meditation realizes his divine nature is a true hero and attains freedom, peace and bliss absolute!
