"Consider the effect of poison. Deadly though it is, it possesseth the power of exerting, under certain conditions, a beneficial influence."

Edward Weston

"It should be borne in mind, however, that when the light of My Name, the All-Pervading, hath shed its radiance upon the universe, each and every created thing hath, according to a fixed decree, been endowed with the capacity to exercise a particular influence, and been made to possess a distinct virtue. Consider the effect of poison. Deadly though it is, it possesseth the power of exerting, under certain conditions, a beneficial influence. The potency infused into all created things is the direct consequence of the revelation of this most blessed Name. Glorified be He, Who is the Creator of all names and attributes! Cast into the fire the tree that hath rot and dried up, and abide under the shadow of the green and goodly Tree, and partake of the fruit thereof."
