Why are words which have been spoken 1500, 2000 or 2500 years ago still repeated today and still helpful?

Why are words of Shantideva, (685 p. Chr n.)

Christian and Buddhist teachings repeated even today 1500 years, 2000 years, 2500 years after they have been spoken for the first time by their authors still repeated today and helpful? Is this because these where authors which where alive, and said thing nobody ever has spoken before and where helpful to other which did not have these words?

Are there any texts and scriptures of Dilgho Kihenze Rhinpoche, are there any texts of Nicholas of Flüe? There are some. But they mainly studied, repeated and taught on the basis of teachings of Shantideva, Buddha, Jesus Christ, but also Jewish teachings. Also Thich Nhat Hanh was a best-selling author, but will his books be read in 2000 years from now?
