The Hebrew alphabet has 22 letters and according to Kabbalah everything has been created on a spiritual level by those 22 forces. But what exactly?
Some teachers say we've 22 chromosomes, but I don't agree, as we've 23 pairs of chromosomes (total of 46). So I can't see any other connections of 22 to the Universe (in terms of the forces or building blocks).
What is special in 22 (twenty two) or what's the deeper meaning of it?
Similar as we've 12 months based on the Moon's phases (12 lunar cycles in a solar year; twelve Shevatim) and we've 12 hours to the day, 12 hours to the night (based on different constellations of the sky), etc.
The topic was discussed at The Kabbalah Centre classes. Please check the podcast at around 16:05, 52:00 minutes (22 forces = 22 building blocks).
