首楞嚴義疏注經 3.512

3.512

三科七大即相即性，本自不生，今則無滅，生滅去來皆如來藏，圓遍不動，清淨本然，此是如來宣勝義中真勝義性，故云微妙開示。身心圓明，故云蕩然。更無諸法可為所疑，故無罣礙。

The three categories and seven great elements are identical to appearances and identical to nature; fundamentally unarisen, they now do not cease. Arising, ceasing, going, and coming are all the tathāgatagarbha, perfectly pervasive and unmoving, pure and fundamentally so. This is the Tathāgata proclaiming the true ultimate nature within the ultimate truth, hence it is called 'subtle and wondrous instruction'. With body and mind perfectly luminous, they are therefore 'completely unburdened'. Since there are no longer any dharmas that can be doubted, there is 'freedom from hindrances'.
