The key to human happiness lies within our own state of mind, and so too do the primary obstacles to that happiness.

Always embrace the common humanity that lies at the heart of us all.

It is important that when pursing our own self-interest we should be 'wise selfish' and not 'foolish selfish'. Being foolish selfish means pursuing our own interests in a narrow, shortsighted way. Being wise selfish means taking a broader view and recognizing that our own long-term individual interest lies in the welfare of everyone. Being wise selfish means being compassionate.

The foundation of the Buddha's teachings lies in compassion, and the reason for practicing the teachings is to wipe out the persistence of ego, the number-one enemy of compassion.

Love and compassion ... are the ultimate source of human happiness, and the need for them lies at the very core of our being.

The need for love lies at the very foundation of human existence.

In the modern world, the interests of a particular community can no longer be considered to lie within the confines of its own boundaries.

Ultimately, the reason why love and compassion bring the greatest happiness is simply that our nature cherishes them above all else. The need for love lies at the very foundation of human existence.

There 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.
