If he cannot stop the mind that seeks after fame and profit, he will spend his life without finding peace. - Dōgen

"Beneficial action" is to benefit all classes of sentient beings skillfully, that is, to care about their distant and near future and to help them by using skillful means. In ancient times, someone helped a caged tortoise; another took care of a sick sparrow. They did not expect a reward; they were moved to do so only for the sake of beneficial action.

Foolish people think that if they help others first, their own benefit will be lost, but this is not so. Beneficial action is an act of oneness, benefiting self and others together.

Only those who have the great capacity of genuine trust can enter this realm [the realm of the buddhas]. Those who have no trust are unable to accept it, however much they hear it.
