According to Osho, wisdom is the simplicity that comes when your inner truth flows unbroken into your words and actions. When mind is natural, spontaneous, and speech expresses exactly what is within, you are real; layers of falseness fall away. In a society built on lies such simplicity may seem disruptive, but it is the only foundation for a truly good life and society.
Wisdom is being simple inside and speaking your real truth, even if it bothers a pretend world.
