Regarding the mystical God-realization, its characteristic experience is not only a "mere" feeling of bliss, but an overwhelming one. This feeling may come without any vision whatsoever, but in several cases a vision does precede the profoundest state of bliss. In such cases it is nearly always a consequence of the devotion given by the devotee either to a living teacher or to a historical saviour. However it is only the accompaniment to the goal and not necessarily a part of the goal itself. Apart from this vision of some human or divine personage, the only other vision which may be experienced at this stage is of an ocean of light surrounding and permeating the mystic. This is only the case in the penultimate stage and vanishes when the highest goal is reached. Along with the bliss, there is a certain intuitive knowledge which may best be described as the knowledge that a divine power is present within the heart and that this power is beneficent, immaterial, and righteous. This knowledge is overwhelming in its certitude to the mystic. However, he must note at this point that this experience concerns the mystic himself, that the realization associates him with God, and does not concern itself with the rest of the world. Whatever else he believes he experiences, or in whichever way he understands these experiences, there will be added the workings of his own intellect or imagination or the unconscious agency of his tendencies. To put the matter briefly, the mystic attains intuitive knowledge that he is a divine self or soul, but the knowledge does not extend beyond that. It gives him no certitude or knowledge about the world outside of his self.
