Brahmajalasutta 2.34

2.34

‘Now of these, brethren, the Tathāgata knows that these speculations thus arrived at, thus insisted on, will have such and such a result, such and such an effect on the future condition of those who trust in them. That does he know, and he knows also other things far beyond (far better than those speculations); and having that knowledge he is not puffed up, and thus untarnished he has, in his own heart, realised the way of escape from them, has understood, as they really are, the rising up and passing away of sensations, their sweet taste, their danger, how they cannot be relied on, and not grasping after any (of those things men are eager for) he, the Tathāgata, is quite set free.
‘These, brethren, are those other things, profound, difficult to realise, hard to understand, tranquillising, sweet, not to be grasped by mere logic, subtle, comprehensible only by the wise, which the Tathāgata, having himself realised and seen face to face, hath set forth; and it is concerning these that they who would rightly praise the Tathāgata in accordance with the truth, should speak.’
