"But what is wisdom ? Where can it be found ? Here we come to the crux of the matter: it can be read about in numerous publications but it can be found only inside oneself. To be able to find it, one has first to liberate oneself from such masters as greed and envy. The stillness following liberation - even if only momentary - produces the insights of wisdom which are obtainable in no other way."
E. F. Schumacher, in Small is beautiful.
