Commiserate with a turtle in trouble, and take care of a sparrow suffering from injury. When you see the distressed turtle or watch the sick sparrow, you do not expect any repayment for your favor, but are moved entirely by your desire to help others.
Therefore serve enemies and friends equally, and assist self and others without discrimination. If you grasp this truth, [you will see that] this is the reason that even grasses and trees, wind and water are all naturally engaged in the activity of benefiting others, and your understanding will certainly serve others' benefit..." Dōgen Zenji
