南宗頓教最上大乘摩訶般若波羅蜜經六祖惠能大師於韶州大梵寺施法壇經 1.30

1.30

"Now that you have taken refuge in the Three Jewels within yourselves, let all of you with a sincere mind listen as I explain the Dharma of mahāprajñāpāramitā for you kalyāṇamitras. Kalyāṇamitras, though you recite it without understanding, Huineng will explain it to you; let each of you listen. Mahāprajñāpāramitā is Sanskrit from the Western regions; in the language of the Tang it means 'great wisdom arriving at the other shore.' This Dharma must be practiced; it does not consist in oral recitation. If you recite it with your mouth but do not practice it, it is like a phantom, like an illusion. For one who cultivates the practice, their dharmakāya is equal to the Buddha. What is called mahā? Mahā means 'great.' The capacity of the mind is vast and great, just like empty space. If you sit in meditation with an empty mind, you will fall into the neutral emptiness. Empty space can contain the sun, moon, stars, planets, the great earth, mountains and rivers, all grasses and trees, evil people and good people, bad phenomena and good phenomena, heavens and hells; they are all within empty space. The emptiness of the nature of worldly people is also like this.
