The common trade of polite words and affirmations is widespread. However, brother, your true nature is distinctly unique.

This couplet talks about a world where interactions are often just a "trade of 'yes, yes' words." It highlights how people might engage in polite, agreeable conversations without much substance or genuine opinion. The second line, "Your true self, brother, is separate," offers a profound insight. It reminds us that even amidst such superficial exchanges, your inherent worth, your true character, and your unique perspective remain distinct and untouched. It's a beautiful message encouraging you to stay true to yourself, recognizing that your individuality is precious and doesn't get diluted by the surrounding polite chatter. Value your unique essence.
