“I try always to be sincere, even towards those who may consider me their enemy.
If I were instead to develop ill-will through anger or hatred who would lose? No one but myself.
My happiness, my ability to sleep well, even my appetite would suffer, but my ill-will alone could not hurt those towards whom it was directed.
The agitation that came with it would instead do nothing but weaken my own constitution”
Dalai Lama <Freedom from Exile>
