注大乘入楞伽經 6.9

6.9

The dharmakāya: knowing dharmas such as the two kinds of selflessness is called the dharmakāya; the rūpakāya: the adornment of major marks and minor signs is called the rūpakāya. Between Buddha and Buddha there is no difference, except for manifesting various types of physical bodies to subdue different sentient beings in various realms. This directly answers how there is no contradiction between being the Buddha and undergoing births in hundreds of thousands of forms; this is called equality of body, free of contradiction.
