In Kabbalah, everything is numbers and mathematics.  The number is holy and infinite.  In the universe everything is measurement and weight.  For the Gnostics, God is a Geometrist.  Mathematics are sacred.  No one was admitted into the school of Pythagoras if they were not knowledgeable about mathematics, music, etc.   Numbers are sacred.

All of the splendors of the world and the extraordinary interplay of the Sephiroth on the thirty-two paths of wisdom within God and within the human being are described in a marvellous way in the Sepher Yetzirah, a very ancient sacred Hebraic book of the Rabbis.

All the science of the Sephiroth is hidden within the mystery of the sexes.  The secret key of the Sepher Yetzirah is within the science of numbers.  Anyone can think in thirty-two ways, but in reality, the thirty-two paths of wisdom are equal to 3 + 2 = 5, equal to the star of five points, the Pentalpha, meaning equal to the human being, which signifies that the paths are within the human being.  Everything is within oneself.  It is written in a very symbolic way; that is why it refers to thirty-two paths.
