The following aphorisms on traits to avoid were written by Patrul Rinpoche, a 19th c. Tibetan master. A contemporary Tibetan lama, Phakchok Rinpoche, gave a teaching on the text that was printed in Tricycle in January, 2016. Here are the aphorisms:
The proud will never be pleased.
The jealous will never be happy.
The greedy will never be satisfied.
The hateful will never be reconciled.
The stingy will never have enough.
The ignorant will never accomplish.
By contrast, here is what the Dalai Lama advised to cultivate happiness and wellbeing:
“If you want others to be happy, practice compassion. If you want to be happy, practice compassion.”
