What is Truth?
Being in these two modes breaks up the idea of truth into existential truth (sammuti sacca) and experiential truth (paramattha sacca). This means there is no such thing as an absolute truth. To hold one idea as truth is to become narrow minded, and to ignore the validity of its opposite. This fact is expressed by the Buddha in the analogy of the elephant and the blind men. The Buddha points out this fact also in the Cula-viyuha Sutta, in the Sutta Nipatha, in verse form as follows:
If truth is one, and no second exists
Debates will never arise among folk
A variety of truths they themselves do form
Gurus therefore never speak of one truth
Ekaṁ hi saccaṁ na dutiyamatthi
Yasmiṁ pajā no vivade pajānaṁ,
Nānā te saccāni sayaṁ thunanti
Tasmā na ekaṁ samanā vadanti
Never was there a variety of truths
Other than sensations always in the world
Creating views using speculative logic
They speak of a duality: falsehood and truth
Na heva saccāni bahuni nānā
Aññatra saññāya niccāni loke,
Takkañca diṭṭhisu kapappayitvā
Saccaṁ musāti dvayadhammamāhu
About The Four-fold Supernormal Reality, the Buddha states:
(1) The first truth is not to be believed, but to be comprehended (pariññeyyam).
(2) The second truth is not to be believed, but to be eliminated (pahātabbaṁ).
(3) The third truth is not to be believed, but to be realized (sacchikātabbaṁ).
