What is Truth?

Everything rests on truth

From Mahabharata The Epic Story of The Great War by Annie Besant, p.181-182

"Truth is an eternal duty. One should reverentially bow to truth. Truth is the highest refuge. Truth is duty; truth is penance; truth is yoga; truth is the eternal Brahman. Truth has been said to be sacrifice of a high order. Everything rests on truth ...
The forms that truth assumes are impartiality, self-control, forgiveness, modesty, endurance, goodness, renunciation, contemplation, dignity, fortitude, compassion and abstention from injury."
