There are 168 red SLs above the 7-tree on the left-hand Pillar of Judgement of the 91 Trees of Life representing CTOL. There are 168 blue SLs above the 7-tree on the right-hand Pillar of Mercy. 168 green SLs span the central Pillar of Equilibrium down to the top of the 7-tree. There are 14 green yods per sector of the Type C dodecagon that are either corners of tetractyses or hexagonal yods at their centres. The 9 tetractyses per sector have 14 sides, a red and a blue hexagonal yod lying on each one. Hence, the 504 yods surrounding the centre of the dodecagon comprise (12×14=168) yods that are either red, green or blue. They symbolise the three sets of 168 SLs lining the three pillars of CTOL down to the top of the 7-tree</span>
