"Holding anger is a poison" is a profound statement from Mitch Albom's book, "The Five People You Meet in Heaven." This quote emphasizes the detrimental effects of harboring resentment and rage. Anger, if left unchecked, can consume one's emotions and hinder personal growth. It suggests that clinging to negative feelings not only affects relationships with others but also one’s own peace of mind.

Albom encourages readers to let go of anger and embrace forgiveness. By doing so, individuals can free themselves from the burdens of negativity and open themselves to healing and understanding. The message highlights the importance of emotional release and the positive impact it can have on one's life and interactions with others.
