Mahamati, all these expressions as applied to the Tathagatas -are without meaning, for that which is none of these is something removed from all measurement, and that which is removed from all measurement turns into a meaningless word; that which is a mere word is something un-born; that which is un-born is not subject to destruction; that which is not subject - to destruction is like space and space is neither effect nor cause; that which is neither effect nor cause is something unconditioned; that which is unconditioned is beyond all reasoning; that which is beyond all reasoning,-that is the Tathagata. The self-nature of Tathagatahood is far removed from all predicates and measurements; the self-nature of Tathagatahood is Wisdom.
