Rabbi Shimon, the son of Rabban Gamliel, warns against exaggerated piety, explaining that it always leads to sin. Rabbi Dunner explains what this means, using the Bartenura commentary to present a path in Judaism that understands extra boundaries in context, based on the story of Adam and Eve in the Garden of Eden. And in the final mishna of the first chapter of Pirkei Avot, Rabban Shimon ben Gamliel enumerates the three foundations of the world's existence, in which justice and truth don't always necessarily align.
