Life always gives us exactly the teacher we need at every moment. This includes every mosquito, every misfortune, every red light, every traffic jam, every obnoxious supervisor (or employee), every illness, every loss, every moment of joy or depression, every addiction, every piece of garbage, every breath. Every moment is the guru.
We sometimes have a flash of understanding that amounts to the insight of genius, and yet it slowly withers, even in our hands - like a flower. The form remains, but the colours and the fragrance are gone.
