The only way to understand what Enlightenment is, is to experience for yourself a mystery that cannot be imagined and a depth that cannot be measured. In that depth, you will find out what it's like to want nothing at all. In that freedom from wanting, there is a peace so profound that the greatest challenge is simply not moving away from it.
Sooner or later after entering the path, we will have the liberating experience of wanting nothing and needing nothing. That is when we discover what our true nature is all about. That is when we fall deep within the Self. Like falling into the mouth of a volcano, down and down and down we go, sinking so deep that we even forget about the falling. When this happens, there is inexpressible contentment because one recognizes that there is absolutely nothing missing.
