Moses was walking in the wilderness looking for fire when he saw from a distance smoke rising on the top of a mountain, so he climbed to the top of the mountain in order to find that fire. But on arriving at the top of the mountain, he saw a glimpse of lightning so powerful that it went throughout his whole being. Moses fell down unconscious on the ground, and when he recovered his senses he found himself with illumination. From that time Mount Sinai was the place where he often went and communicated with God. This story is very enlightening when one thinks that it is possible that all the illumination that is desired can come to a soul in a moment.
