In the Mahayana classics, the elaboration about “accomplishing Buddhahood” can be expanded from the three angles of Dharmakaya, Sambhogakaya and Nirmanakaya. Among these the most basic and the core is accomplishing Dharmakaya Buddha. The key of accomplishing Dharmakaya Buddha lies in eradicating the attachment to inherently existent self and the attachment to external objects, immediately corresponding with Tathata. Zen School turns the theory of Mahayana classics into the body and mind practice with a distinctive style. In view of the persons that attach the classics words and the external images , it especially adopts the ruthless method of “scolding Buddha and blaming masters” in order to make them give up the attachment, see the nature, realize Tathata and accomplish Buddhahood. From the superficial form of “scolding Buddha and blaming masters”, we can see the real spirit of “becoming Buddhahood and masters” exactly.
