Energy points for 108

There are said to be 108 energy lines, or nadis, converging to form the heart chakra. Marma points are like Chakras, or intersection of energy, with fewer converging energy lines. On Sri Yantra, the Marmas have 54 intersecting energy lines where three lines intersect. Each has feminine, or shakti, and masculine, or shiva, qualities. 54 X 2 = 108. Therefore there are 108 points that define the human body and the Sri Yantra or the Yantra of Creation. The same rule is observed in the Sanskrit language, with its 54 letters, both representing the two genders and they are also called Shiva and Shakti respectively; again, 54 X 2= 108.
