17. If your hand be the cause of offence, cut it off. This is a very strong statement and it would be absurd for it to be taken in its literal sense. It should therefore be understood that each one must destroy within themselves everything that might cause offence, that is to say all evil, by rooting out every impure thought and every tendency towards violence, corruption or depravity. It also means that it is preferable for a man to cut off a hand rather than use it to commit an evil action, or better still, to lose one's sight rather than allow one's eyes to conceive bad thoughts. For those who take the trouble to discover the allegoric meaning of His words, Jesus never said anything that was absurd. Nevertheless, many things cannot be understood without the key to decipher them and this key is offered to us through Spiritism.
