大方便佛報恩經 3.36

3.36

"Then her father went up to the top of a high mountain and watched his daughter from afar, not looking away for even an instant. He thought to himself: 'Now I watch my daughter from afar; she is going far away and disappearing from sight. When I return to my original dwelling, I will wail in anguish, my eyes filled with streaming tears. I raised this daughter while she knew nothing, and now she is parting far from me.' He thought further: 'I should remain standing here and not turn away. Why? If my daughter looks back behind her and does not see me, it will cause her sorrow and grief.' After standing there for a long time, the daughter went out of sight, never having turned her head to look back.
