specific detail? What I would like to read about is the symptoms
he got when being in the pitch-black darkness.
Thank you in beforehand

There is a fundamental difference between Divine Revelation as vouchsafed by God to His Prophets, and the spiritual experiences and visions which individuals may have. The latter should, under no circumstances, be construed as constituting an infallible source of guidance, even for the person experiencing them.
(From a letter written on behalf of Shoghi Effendi dated November 1, 1940, to an individual believer, Lights of Guidance, no. 1741)

difference between Baha'u'llah's experience while in the prison and the Kundalini experience. In many cases Kundalini awareness takes place
without the person knowing it, while in Baha'u'llah's experience he was
aware of this occurence and even used the me as "Me" something
more then just an experience. However this is only my opinion.
The calling of our assistance of works of grace is one of these aberrations and cannot be adopted into the maxims of reason, if she is to remain within her limits; as indeed can nothing of the supernatural, simply because in this realm all use of reason ceases. For it is impossible to find a way to define these things theoretically ([showing] that they are works of grace and not inner natural effects) because our use of the concept of cause and effect cannot be extended beyond matters of experience, and hence beyond nature. Moreover, even the hypothesis of a practical application of this idea is wholly self-contradictory. For the employment of this idea would presuppose a rule concerning the good which (for a particular end) we ourselves must do in order to accomplish something, whereas to await a work of grace means exactly the opposite, namely, that the good (the morally good) is not our deed but the deed of another being, and that we therefore can achieve it only by doing nothing, which contradicts itself. Hence we can admit a work of grace as something incomprehensible, but we cannot adopt it into our maxims either for theoretical or for practical use.
