Thinking that practice and enlightenment are not one is no more than a view that is outside the Way [that is, deluded]. In buddha-dharma, practice and enlightenment are one and the same. Because it is the practice of enlightenment, a beginner’s wholehearted practice of the Way is exactly the totality of original enlightenment. For this reason, in conveying the essential attitude for practice, it is taught not to wait for enlightenment outside practice. This must be so because [this practice] is the directly indicated original enlightenment. Since it is already the enlightenment of practice, enlightenment is endless; since it is the practice of enlightenment, practice is beginningless.
