妙法蓮華經玄義 4.64

4.64

兜率陀天有，用青色三昧破者。真諦三藏云：「此天果報樂青，宮殿服玩等一切皆青。」菩薩為破諸青，修第一義，非青黃赤白，而見青黃赤白。第一義非戒、定、慧，而戒、定、慧。以戒破果報青；以生無生慧破見思青。非真見真，非假見假，非中見中，亦復如是。三青障破，自成三諦三青三昧。乃至感應成他三昧，例上可解。

As for the existence of the Tuṣita Heaven being destroyed by the blue-color samādhi: Tripiṭaka Master Paramārtha said, 'The retribution of these devas takes pleasure in blue; palaces, clothing, ornaments, and everything else are all blue.' In order to destroy these blues, the bodhisattva cultivates the paramārtha, which is neither blue, yellow, red, nor white, yet sees blue, yellow, red, and white. The paramārtha is neither precepts, meditation, nor wisdom, yet it is precepts, meditation, and wisdom. With precepts he destroys the blue of retribution; with wisdom of arising and non-arising he destroys the blue of views and thoughts. Not being the true yet seeing the true, not being the provisional yet seeing the provisional, and not being the Middle yet seeing the Middle are also like this. When the three obstructions of blue are destroyed, he personally perfects the three-blue samādhi of the three truths. Up to stimulus and response perfecting the samādhi for others, it can be understood by analogy with the above.
