Until recently, no Kabbalist was able to reveal the way of studying Kabbalah openly, publicly, and explain every word of this science. Only the last Kabbalist of the 20th century, Y. Ashlag, (the Baal HaSulam) could reveal and explain in his works the path to the Purpose of creation that is suitable for all. This is called "The Path of dressing."
The revelation of this world and the order of its existence is an amazing science. In the same way, the revelation of the Creator's light in the world as a reality of levels and modes of influence constitutes a wonderful science as well.
