Quote by Gotthold Ephraim Lessing
The most deadly fruit is borne by the hatred which one grafts on an extinguished friendship.

Summary
This quote emphasizes the destructive power of harboring hatred towards someone with whom you previously had a close and meaningful relationship. It suggests that when we hold onto intense hostility and bitterness towards someone we once considered a friend, it becomes a poisonous fruit that has the potential to cause great harm. The metaphor of "grafting" emphasizes how this animosity is artificially cultivated and attached to a bond that was once strong, magnifying its detrimental impact. It reminds us of the importance of letting go of negativity and nurturing positive relationships instead.
