佛說佛名經 16.15

16.15

「第四發菩提心者，經言：『當樂佛身。』佛身者即法身也。從無量功德智慧生，從六波羅蜜生，從慈悲喜捨生，從三十七助菩提法生，從如是等種種功德智慧生如來身。欲得此身者，當發菩提心求一切種智，常樂我淨薩婆若果，淨佛國土成就眾生，於身命財無所悋惜。

"Fourth, regarding generating the bodhicitta: a sūtra says: 'One should delight in the body of the Buddha.' The Buddha's body is none other than the Dharmakāya. It is born of measureless merit and wisdom; born of the six pāramitās; born of loving-kindness, compassion, sympathetic joy, and equanimity; born of the thirty-seven factors contributing to awakening; born of such various kinds of merit and wisdom is the body of the Tathāgata. Those who wish to obtain this body should generate the bodhicitta to seek omniscience, the fruit of sarvajña which is permanence, bliss, self, and purity, to purify the Buddha-fields and bring sentient beings to maturity, begrudging nothing of their body, life, or wealth.
