Silent illumination is the realization of … wakefulness, stillness and awareness… all of which are different ways to describe mind’s natural state. Experiencing it for the first time is like suddenly dropping a thousand pounds from your shoulders – the heavy burdens of self-attachment, vexations, and habitual tendencies. Self-attachment, vexations, and habitual tendencies run deep. So practitioners must work hard to experience enlightenment again and again until they can simply rest in mind’s natural state. The key is to practice diligently but seek no results.
