27.12

Answer: The source is not a number or quantity: it is neither one nor three. Though spoken of pervading sands of the Ganges, it is both three and one. The Commentary says: 'Formerly, to destroy heresy, one was spoken of as three, yet three did not contradict one. Now, to destroy differentiation, three is spoken of as one, yet one does not contradict three.' Such threeness and oneness are indeed the realm of all Buddhas. Therefore it is said: relying on substance there is function, so one does not contradict three; relying on function there is substance, so three does not contradict one. Substance and function are sovereign; refutation and establishment are unimpeded.
