you only have one head

you have only one head and look after it for it's a marvelous thing. no machinery, no electronic computers can compare with it. it's so vast, so complex, so utterly capable, subtle and productive. it's the storehouse of experience, knowledge, memory. all thought springs from it. what it has put together is quite incredible: the mischief, the confusion, the sorrows, the wars, the corruptions, the illusions, the ideals, the pain and misery, the great cathedrals, the lovely mosques and the sacred temples. it is fantastic what it has done and what it can do. but one thing it apparently cannot do: change completely its behavior in its relationship to another head, to another human being.

neither punishment nor reward seem to change its behavior; knowledge doesn't seem to transform its conduct. the 'me' and the 'you' remain. it never realizes that the 'me' is the 'you', that the observer is the observed. its love is its degeneration; its pleasure is its agony; the gods of its ideals are its destroyers. its freedom is its own prison; it is educated to live in this prison, only making it more comfortable, more pleasurable. you have only one head, care for it, don't destroy it. it's so easy to poison it."
