For those who investigate by wisdom-eyes, the truth (sacca) is not perverted like (the object of) magic trick, is not deceptive/would not cause to say untruth like a mirage, and is not undiscoverable ultimately like the "self" of heretical teachers. But rather the truth (sacca) is only the domain (object) of Noble Ones’ knowledge According to the explanation below, "ariyañāṇa" means Noble Ones' knowledge. This word includes the Noble One's knowledge arose depending on the Path Knowledge [ariyañāṇassāti ariyānaṃ ñāṇassa. Tena ariyānaṃ maggañāṇānusārena pavattanakañāṇampi saṅgahitaṃ hoti. (Vibhaṅga-anuṭīkā)] by being true, unperverted, and real in the form of oppression, origin, peace, and way of escape. (Just as the characteristic of fire and the nature of the world, this truth, unperverted state, reality is the meaning of “sacca” (truth), thus should be understood. )

This is why the Buddha said --

“Bhikkhus, whatever is said as "this is suffering", this is real, this is not unreal, this is not otherwise.”

Furthermore-

As suffering is not without oppressing, other than suffering there is nothing which oppress;

Therefore, with the certainty of oppression, this (suffering) is known as the truth.

Without it, because of other, there is no suffering; because of it there is not without that suffering;

Thus, with certainty as the cause of suffering, craving is known (matā) as the truth.

As apart from Nibbāna, there is no peace; that Nibbāna is not without peace;

Therefore, with certainty of the peace, this (Nibbana) is known as the truth.

Apart from the Noble Path there is no way of escape; that Path is not without the way of escape;

Thus, because of being the real way of escape, it is agreed upon as the truth.

Thus, the truth, unperverted state, reality in regards to the four truths such as suffering,

Generally, the wise said as the meaning of the truth (saccaṭṭha).
