231 Gates

231 Gates
The idea here is that there are 231 pairs of letters. (proof: 22 choices for the first letter, 21 choices for the second letter, modulo order. (22*21)/2 = 231). If we imagine the complete graph with 22 nodes, we have a good picture of the 231 Gates:

The alchemical process suggested by the formula solve et coagula indicates that the initial stages of growth correspond to study and contemplation of each of the 10 Sephiroth and each of the 22 letters (separate). This is the planting of the seeds. The letters are then combined and studied in pairs, contemplating the inner correlations between things apparently different (recombine). The first (lesser) initiation is complete when all 231 Gates have been opened.
