If we put emphasis on the truth itself, rather than its spiritual or physical being, that is Dharmakaya Buddha.
Although he is the embodiment of the truth, without practice he cannot
attain enlightenment or he cannot express the truth. Only when he actually
practice the truth, the truth will be realized. Realization of the truth will
take place in this sense. We called him then Sambhogakaya Buddha. -------------------------------------------------- Excerpt from Shunryu Suzuki lecture - 68-01-11B as found on shunryusuzuki.com. Edited by DC
