It is an inner aspiration to know, to enter into contact and union with the greater Reality beyond, which also pervades the universe and dwells in us, and, as a result of that aspiration, that contact and that union, a turning, a conversion, a birth into a new being. In her attempt to open up the inner being, Nature has followed four main lines - religion, occultism, spiritual thought and an inner spiritual realization and experience. Only spiritual realization and experience can achieve the change of the mental being into a spiritual being. Mysticism and spirituality have been criticized from two points of view. The mystic turns away from life.
Mystical knowledge is purely subjective.
If the final goal of terrestrial evolution were only to awaken man to the supreme Reality and to release him from ignorance and bondage, so that the liberated soul could find elsewhere a higher state of being or merge into this supreme Reality, the task would be accomplished with the advent of the spiritual man. But there is also in us an aspiration for the mastery of Nature and her transformation, for a greater perfection in the earthly existence itself. To be established permanently, this new order of existence demands a radical change of the entire human nature. In this transformation, there are three phases. Three ways thus open before the seeker.
