Why don't people believe in the teachings of great mystics?

According to Osho, people don’t believe mystics because understanding follows longing, and most people long for money, sex, or forgetfulness, not truth. Their language is tuned to their desires, while mystics speak paradox and silence from a different state of remembrance. To the “asleep,” mystics seem mad; they’re tolerated or worshipped yet not heard. Real understanding needs initiation—an inner shift into the same experiential frequency.

You can’t really get what a mystic is saying unless you want what they want and taste it yourself; otherwise it sounds like nonsense.
