Man's real genius and knowledge remains preserved in books

The sources of our knowledge of the kabalistic doctrines are the books of Yetzirah and Zohar, the former drawn up in the second century, and the latter a little later; but they contain materials much older than themselves...In them, as in the teachings of Zoroaster, everything that exists emanates from a source of infinite Light.

Force, unregulated or ill-regulated, is not only wasted in the void, like that of gunpowder burned in the open air, and steam unconfined by science; but, striking in the dark, and its blows meeting only the air, they recoil, and bruise itself.

He who endeavors to serve, to benefit, and improve the world, is like a swimmer, who struggles against a rapid current, in a river lashed into angry waves by the winds. Often they roar over his head, often they beat him back and baffle him. Most men yield to the stress of the current... Only here and there the stout, strong heart and vigorous arms struggle on toward ultimate success.

One man is equivalent to all Creation. One man is a World in miniature.

That which causes us trials shall yield us triumph: and that which make our hearts ache shall fill us with gladness. The only true happiness is to learn, to advance, and to improve: which could not happen unless we had commenced with error, ignorance, and imperfection. We must pass through the darkness, to reach the light.

Virtue is but heroic bravery, to do the thing thought to be true, in spite of all enemies of flesh or spirit, in despite of all temptations or menaces.
