A mind that is characterized by unrest will not be tranquil even in the presence of great calm.
Dalai LamaThere is no self-interest completely unrelated to others' interests. Due to the fundamental interconnectedness which lies at the heart of reality, your interest is also my interest. From this it becomes clear that "my" interest and "your" interest are intimately connected. In a deep sense, they converge.
