Life is an experimental journey undertaken involuntarily. It is a journey of the spirit through the material world and, since it is the spirit that travels, it is the spirit that is experienced. That is why there exist contemplative souls who have lived more intensely, more widely, more tumultuously than others who have lived their lives purely externally. The end result is what matters. What one felt was what one experienced. One retires to bed as wearily from having dreamed as from having done hard physical labor. One never lives so intensely as when one has been thinking hard.
Sit still with me in the shade of these green trees, which have no weightier thought than the withering of their leaves when autumn arrives, or the stretching of their many stiff fingers into the cold sky of the passing winter. Sit still with me and meditate on how useless effort is, how alien the will, and on how our very meditation is no more useful than effort, and no more our own than the will. Meditate too on how a life that wants nothing can have no weight in the flux of things, but a life the wants everything can likewise have no weight in the flux of things, since it cannot obtain everything, and to obtain less than everything is not worthy of souls that seek the truth.
Giving importance to what we think because we thought it, taking our own selves not only (to quote the Greek philosopher) as the measure of all things but as their norm or standard, we create in ourselves, if not an interpretation, at least a criticism of the universe, which we don't even know and therefore cannot criticize. The giddiest, most weak-minded of us then promote that criticism to an interpretation that's superimposed, like a hallucination; induced rather than deduced. It's a hallucination in the strict sense, being an illusion based on something only dimly seen.
