Thought of Rav Kook:
R. Shvat
The world is constantly undergoing evolution. Just like sports records and technology are constantly improving, and mankind is constantly maturing (e.g. slowly but surely getting rid of slavery, racism, chauvinism, ;imperialism, etc.), how much more so is it natural for me, the individual, who has free-will to destine his fate, to constantly improve, and that's what Elul is about! (Orot HaTshuva of Rav Kook)
