What are the precepts of the Lord?

There is nothing in the elements of Nature capable of effecting changes equal to the mind in its onward march. Its ameliorating propensities change with the fluctuation of sentiment, swaying the mind from peace to war or from war to peace. Mental changes displace error and establish right precepts, which dictate and guide onward, strengthening our purposes more and more to uphold that equality and freedom, which involve the morals and our good.
