In Sanskrit script the sound i is written in the form of three dots in a triangle （∴）. Since these three line up with each other either horizontally or vertically， it is used as a trope for "neither the same nor different." In the Nirva^na-su^tra it is used as a trope for the relationship between the dharma-body 法身， Abhidharmako/sa and moks!a 解脱.
