The dustless and stainless Eye of Truth (Dhamma-cakkhu) has arisen.
He has seen Truth, has attained Truth, has known Truth, has penetrated into Truth, has crossed over doubt, is without wavering.
Thus with right wisdom he sees it as it is (yatha bhutam) ... The Absolute Truth is Nibbana, which is Reality. (Buddha, from the Dhatuvibhanga-sutta (No. 140) of the Majjhima-nikaya)
