There is the law of reverence.

Conscious of vastness and sublimity, in the presence of mountains, man, frail, ignorant, passing swiftly to his grave, is asked to bow his head in the presence of the Eternal One.
There is also the law of truth in speech, the law of purity in thought, the laws that forbid theft and covetousness and killing.

But all these laws are gathered up and fulfilled in love, just as the seven colors of nature are gathered up and fulfilled in the one white sunbeam.

And he who loves will fulfill all these laws.

Loving himself, man will not waste his physical treasure.
