首楞嚴義疏注經 6.306

6.306

'When purity is ultimate' means the full purity of liberation is perfected. 'Light penetrates everywhere' means the full enlightenment of prajñā is complete. 'Tranquil illumination' means the true principle of the dharmakāya is consummate. When the three virtues are perfected, the three obstructions are forever ended, like awakening from a great dream, like a lotus blossoming. Turning back to view the world, who could obstruct or retain you? This is the ultimate realization.
