Madness is the first step towards unselfishness. Be mad and tell us what is behind the veil of "sanity". The purpose of life is to bring us closer to those secrets, and madness is the only means.
But this is not a world of free freights. One pays according to an iron schedule--for every strength the balanced weakness; for every high a corresponding low; for every fictitious god-like moment an equivalent time in reptilian slime. For every feat of telescoping long days and weeks of life into mad magnificent instants, one must pay with shortened life, and, oft-times, with savage usury added.
