Nothing is more creative than death, since it has the whole secret of life. It means that the past must be abandoned, that the unknown cannot be avoided, that 'I' cannot continue, and that nothing can be ultimately fixed. When a man knows this, he lives for the first time in his life. By holding his breath, he loses it. By letting go he finds it.
Alan WattsThe animal tends to eat with his stomach, and the man with his brain. When the animal's stomach is full, he stops eating, but the man is never sure when to stop. When he has eaten as much as his belly can take, he still feels empty, he still feels an urge for further gratification.
Alan Watts
