From the outside, the wise and the ignorant may look like they are doing the same thing. Both go to work. Both raise families. Both fulfill their obligations. The difference is invisible. It lives in the heart.
The ignorant person works driven by attachment: I want this result, I need that reward. The wise person does the same work, but without clinging. And the reason the wise person continues to act is not personal need. It is lokasangraha — the desire to hold the world together, to keep the social fabric intact, to serve as a steady example.
