Give thy blow to the ax, and the ax will return the fallen tree, with strong tools for thy arm.

Give thy brain sleep and rest and thy brain will give thy thought nimbleness.

Give thy mind to rocks, and the rock pages will give thee wealth of wisdom.

Give thy thought to the fire and water, and they will give thee an engine stronger than tamed lions.

Give thy scrutiny to the thunderbolt leaping from the east to the west, and the lightnings shall give themselves back to thee as noiseless and gentle and obedient as the sunlight.
