visible world and its hidden mysteries, without a veil, just as lightning or the celestial rays impress the external eye.
The second proof of the existence of these windows in the heart, is that no individual is destitute of these spiritual susceptibilities and of the faculty of thought and reflection. For instance every individual knows by inspiration, things which be has neither seen nor heard, though he knows not from whence or by what means he understands them. Still, notwithstanding the heart belongs to the invisible world, so long as it is absorbed in the contemplation of the sensible world, it is shut out and restrained from contemplating the invisible and spiritual world.
Think not, thou seeker after the divine mysteries! that the window of the heart is never opened except in sleep and after death. On the contrary, if a person calls into exercise, in perfection, holy zeal and austerities, and purifies his heart from the defilement of blameable affections, and then sits down in a retired spot, abandons the use of his external senses, and occupies himself with calling out "O God ! O God !" his heart will come into harmony with the invisible world, he will no longer receive notions from the material world, and nothing will be present in his heart but the exalted God. In this revelation of the invisible world, the windows of the heart are opened, and what others may have seen in a dream, he in this state sees in reality. The spirits of angels and prophets are manifested to him and he holds intercourse with them. The hidden things of earth and heaven are uncovered to him, and to whomsoever these things are revealed, mighty wonders are shown, that are beyond description. As the prophet of God says: "I turned towards the earth, and I saw the east and the west." And God says in his word : "And thus we caused Abraham to see the kingdom of heaven and earth," which is an example of this kind of revelation.
