On Holy Spirit: Rational and Supra-rational Knowledge

"'But the bounty of the Holy Spirit gives the true method of comprehension which is infallible and indubitable. This is through the help of the Holy Spirit which comes to man, and this is the condition in which certainty can alone be attained.' Adu'l-Bahá, Some Answered Questions, p.297) In other words, while we may begin with reason, reason alone cannot reach the heights of knowledge. The supra-rational ways of knowing, i.e. intuition, feeling, and mystical experiences empowered and guided by the Holy Spirit as manifest in the Writings and Institutions is necessary to complete our rational knowledge. In other words, the philosophy embedded in the Writings has an architectonic structure that accommodates rational and supra-rational knowledge."
