Rabbi Yehuda HaNassi

Which is the right path for man to choose for himself? Whatever is harmonious for the one who does it, and harmonious for mankind.

Be as careful with a minor mitzvah as with a major one, for you do not know the rewards of the mitzvot. Consider the cost of a mitzvah against its rewards, and the rewards of a transgression against its cost.

Contemplate three things, and you will not come to the hands of transgression: Know what is above from you: a seeing eye, a listening ear, and all your deeds being inscribed in a book.
