Tenzin Gyatso, The 14th Dalai Lama, (b.1935), talks about “Afflictive emotions” as – our jealousy, anger, hatred, fear and it can be put to an end. When you realize that these emotions are only temporary, that they always pass on like clouds in the sky, you also realize they can ultimately be abandoned.
His Holiness also points out the connection between suffering and afflictive emotions, the “enemy within”. The real enemy is always within, not without. As long as it remains there, lasting happiness cannot be achieved. He shares once you have made up your mind to tackle this “enemy within”, to make it count, you realized the true aspiration to seek freedom from suffering. This is called “renunciation” in Buddhist terms. In this case, afflictive emotions can be a stumbling block to enlightenment. Read more Dharma 101.1: Afflictive Emotions.
The Dalia Lama has written a book exclusively dedicated to afflictive emotions, Destructive Emotions: A Scientific Dialogue with the Dalai Lama.
