What this quote means

Singer's quote highlights the unity of the self: betraying another is betraying oneself. Betrayal erodes our integrity, our self-image, and distances us from our values. It resonates with those who have experienced betrayal, or who have given in to the temptation to betray. It reminds us that our actions toward others define us, and that loyalty is a gift we give ourselves.

How to apply it daily
