To keep the spirit in proper condition is as difficult or even more difficult than cultivating a delicate plant in a greenhouse, where a little more sun may spoil it, a little more water may destroy it, a little more air may be bad for it. The spirit is even more delicate than that. A slight shadow of deception, a mere feeling of dishonesty, a little touch of hypocrisy can spoil it. If fear touches it, if doubt shakes it, if anger strikes deep into its root, it is spoiled. And the more delicate the spirit, the more delicate the care it needs; it must be carefully guarded in the greenhouse. A slight sense of dishonor, the least insult coming from any side, can kill it.
