It is not enough, however, simply to know them. Witness is even more important than knowledge; or rather, it is applied knowledge. The commandments are not imposed upon us from without; they do not diminish our freedom. On the contrary: they are strong internal incentives leading us to act in a certain way. At the heart of them we find both grace and nature, which do not allow us to stay still. We must walk. We are motivated to do something in order fulfil our potential. To find fulfilment through action is, in reality, to become real. To a large extent, from the time of our youth, we are whatever we want to be. We are, so to speak, the work of our own hands.
