“What does it mean to be crazy? To have a disorder of the mind. But "disorder" can only exist if there is some kind of pre determined "order" set in place. And who decides on order relative to the human mind? Human society. Sane and insane is a judgment based on perspective. And according to many other perspectives within this universe, it is human society that is rampant with disorder. So there is no reason to think of yourself as insane; if the very mindset of the society that determines whether you are sane or insane… is in and of itself insane!”

Teal Swan (1984) American spiritual teacher

“I think we must see this very clearly right at the beginning — that if one would solve the everyday problems of existence, whatever they may be, one must first see the wider issues and then come to the detail.”

Jiddu Krishnamurti (1895–1986) Indian spiritual philosopher

Vol. XI, p. 62
Posthumous publications, The Collected Works
Context: I think we must see this very clearly right at the beginning — that if one would solve the everyday problems of existence, whatever they may be, one must first see the wider issues and then come to the detail. After all, the great painter, the great poet is one who sees the whole — who sees all the heavens, the blue skies, the radiant sunset, the tree, the fleeting bird — all at one glance; with one sweep he sees the whole thing. With the artist, the poet, there is an immediate, a direct communion with this whole marvellous world of beauty. Then he begins to paint, to write, to sculpt; he works it out in detail. If you and I could do the same, then we should be able to approach our problems — however contradictory, however conflicting, however disturbing — much more liberally, more wisely, with greater depth and colour, feeling. This is not mere romantic verbalization but actually it is so, and that is what I would like to talk about now and every time we get together. We must capture the whole and not be carried away by the detail, however pressing, immediate, anxious it may be. I think that is where the revolution begins.
