If "logic" here means "underlying rational structure," then the logic of 108 is the mathematical harmony that connects microcosm (human body, 108 marmas or pressure points) to macrocosm (celestial ratios). This is not formal logic but a symbolic or metaphysical logic—a way of reasoning by analogy and numerical correspondence.
To understand the "logic" behind 108, one must look at the number itself. 108 is a Harshad number (divisible by the sum of its digits: 1+0+8=9; 108/9=12). More importantly, it appears consistently in sacred geometry and astronomy. logic 108
