Hello C2!
Just to be clear - some schools of Buddhism wouldn’t accept this. To cling to absolutes without direct experience is antithetical to Buddhist practice. However, if one left one’s mind open, one can accept it. I want to give you some quotes from Mahatma Ghandi on truth and where to find it.
"What is Truth?
What is truth? A difficult question, but I have solved it for myself, by saying that it is what the voice within tells you. How then, you ask, do different people think of different and contrary truths?
It is because we have at the present moment everybody claiming the right of conscience without going through any discipline whatsoever; there is so much untruth being delivered in a bewildered world. All that I can, in true humanity, persent to you is that truth is not to be found by anybody who has not got an abundant sense of humility. If you would swim on the bosom of the ocean of truth, you must reduce yourself to zero.
Truth is within ourselves. There is an inmost center in us all, where truth abides in fullness. Every wrongdoer knows within himself that he is doing wrong, for untruth cannot be mistaken for truth. Truth and righteousness must for ever remain the law in God’s world.
That law of truth is merely understood to mean the we must speak the truth. But we understand the word in a much wider sense. There should be truth in thought, truth in speech, and truth in action.
Truth is the Source of Character
Character is based on virtuous action, and virtuous action is grounded on truth. Truth, then, is the source and foundation of all things that are good and great. Hence fearless and unflinching pursuit of the ideal of truth and righteousness is the key of true health, as of all else.
How to Realize Truth
But how is one to realize truth, which may be likened to the philosopher’s stone or the cow of plenty? By single-minded devotion, abhyasa, and indifference to every other interest, vairagya.
Silence is a great help to a seeker after truth like myself. In the attitude of silence, the soul finds the path in clearer light, and what is elusive and deceptive resolves itself into crystal clearness. Our life is a long arduous quest after truth, and the soul requires inward restfulness to attain its full height.
Experience has taught me that silence is a part of the spiritual discipline of a votary of truth. Proneness to exaggerate, to suppose or to modify truth, wittingly or unwittingly, is a natural weakness of man, and silence is necessary in order to surmount it. A man of few words will rarely be thoughtless in his speech. He will measure every word."
