You have a field. If you sow good and bad seeds in it at the same time, both will grow together, for the soil nourishes all seeds. You cannot convince it that this is stupid, that it should suppress the bad seeds and only let the good ones grow, because it will reply, ‘I don’t understand what you are saying. I protect all seeds and make them grow. To me, everything is good; even the bad is good.’
If you send out good thoughts, nature will feed them and make them strong, and the harvest will be magnificent. But it will also feed your negative thoughts, because the bad seeds are also free to grow.
Until when? Until the harvest, when the farmer gives the order for the weeds to be thrown on the fire and the granary to be filled with the good grain. This is what Jesus taught in the parable of the weeds and the wheat. He knew that evil, like good, has a right to grow and that it is up to humans not to sow it.
