14. Buddha-Nature is the Common Source of Morals.

Furthermore, Buddha-nature or real self, being the seat of love and the nucleus of sincerity, forms the warp and woof of all moral actions. He is an obedient son who serves his parents with sincerity and love. He is a loyal subject who serves his master with sincerity and love. A virtuous wife is she who loves her husband with her sincere heart. A trustworthy friend is he who keeps company with others with sincerity and love. A man of righteousness is he who leads a life of sincerity and love. Generous and humane is he who sympathizes with his fellow-men with his sincere heart. Veracity, chastity, filial piety, loyalty, righteousness, generosity, humanity, and what not-all-this is no other than Buddha-nature applied to various relationships of human brotherhood. This is the common source, ever fresh and inexhaustible, of morality that fosters and furthers the interests of all. To-ju¹ expresses the similar idea as follows:

"There exists the Inexhaustible Source (of morality) within me.
It is an invaluable treasure.
It is called Bright Nature of man.
It is peerless and surpasses all jewels.
The aim of learning is to bring out this Bright Nature.
This is the best thing in the world.
Real happiness can only be secured by it."

Thus, in the first place, moral conduct, which is nothing but the expression of Buddha-nature in action, implies the assertion of self and the furtherance of one's interests. On this point is based the half-truth of the Egoistic theory. Secondly, it is invariably accompanied by a feeling of pleasure or satisfaction when it fulfils its end. This accidental concomitance is mistaken for its essence by superficial observers who adhere to the Hedonistic theory. Thirdly, it conduces to the furtherance of the material and spiritual interests of man, and it led the Utilitarians to the confusion of the result with the cause of morality. Fourthly, it involves the control or sacrifice of the lower and ignoble self of an individual in order to realize his higher and nobler self. This gave rise to the half-truth of the Ascetic theory of morality.
