Things in Themselves Are Not Mutually Different

All things and phenomena, being identical in essence with the Buddha or Reality, are eternal and unchangeable au fond, and, in their true nature, one and the same as each other. The vulgar see variety where Buddhas perceive identity. This inability to see anything beneath the external variety in things arises from confusion in the minds of those who look at them. Things in themselves are not mutually different.
