ཇི་སྐད་སྨྲས་པ་དེ་བཞིན་ཏེ།
Su­bhūti, there is nothing at all that would, apart from the real nature, abide in the real nature; that would, abiding in the real nature, attain manifestly perfect buddhahood in unsurpassed, genuinely perfect enlightenment; and that would, abiding in the real nature, teach the sacred doctrine to sentient beings.
