佛說觀普賢菩薩行法經 1.52

1.52

"Then the voice in the sky speaks these words: 'Śākyamuni is named Vairocana, pervading all places; that Buddha's dwelling place is named Ever Tranquil Light: the place formed by the gathering of the pāramitā of permanence, the place established by the pāramitā of self, the place where the pāramitā of purity extinguishes the marks of existence, and the place where the pāramitā of bliss does not abide in the marks of body and mind. It is the place where the marks of dharmas as existent or non-existent are not seen, like tranquil liberation up to the perfection of wisdom (prajñāpāramitā), because this form is an eternally abiding dharma. Thus should you contemplate the Buddhas of the ten directions.'
