法華論疏 2.64

2.64

示現如來得自在力故者，釋上正念不動及如實智觀，以定力自在得身心不動及如實觀察。如來入定無能驚愕者，釋安詳而起。以無外緣驚愕故，得安詳起定也。前明內有自在之力，今明無外緣愕，竝是歎無量義定有此二力。

Regarding 'to manifest that the Tathāgata has attained sovereign power': this explains the preceding 'right mindfulness unmoving' and 'contemplating with knowledge as it truly is'; through the sovereignty of the power of samādhi, he attains immobility of body and mind and observation as it truly is. 'When the Tathāgata enters samādhi, no one can startle him' explains 'arose calmly.' Because there are no external conditions to startle him, he is able to arise calmly from samādhi. The former clarifies that inwardly he possesses sovereign power; the present clarifies that there is no startling from external conditions. Both praise the samādhi of immeasurable meanings as possessing these two powers.
