Mankind has always had a connection to this planet and the bounty she produces, apart from food; none more so than for use in magic, health and healing. As the following extract from the opening section of 'The Knight's Bible' explains the earth also produces many poisons, yet also the ant-dote - thus keeping a perfect balance. When we walk upon this earth as practitioners of magic and healing, right from the very beginning of our earthly journey we acknowledge the many gifts that this planet has to offer and that freedom, fervency and zeal are thus represented by Chalk, Charcoal and Clay. There is nothing freer than Chalk, the slightest touch of which leaves a trace; there is nothing more fervent than Charcoal, for to it, when properly ignited, the most obdurate metals will yield; there is nothing more zealous than Clay, our mother Earth, for it alone of all the elements has never proved unfriendly to man.
