妙法蓮華經玄義 4.65

4.65

The yellow-color samādhi destroys the existence of the Nirmāṇarati Heaven, the red-color samādhi destroys the existence of the Paranirmitavaśavartin Heaven, and the white-color samādhi destroys the existence of the first dhyāna; these are all retribution. As for white and the rest, by analogy with the blue-color samādhi, the general sense can be understood. As for the white-color samādhi: the first dhyāna is white because it is free from the five desires; because it is not yet free from coarse examination and subtle investigation, it is black. Views and thoughts, dust and sand, fundamental ignorance, and the like are black; destroying these blacks and cultivating the white of various practices, he personally perfects the samādhi. He also perfects the samādhi for others, as explained above.
