For Chih-i, the … differentiation of the coarse and the subtle is for the purpose of reaching non-distinction, since the intention of the Buddha is for universal salvation. Ultimately speaking, the coarseness and the subtlety are all merged in the Lotus Sūtra, for the Buddha made decisive and clear that all of them are dissolved in the subtlety (Chüeh-liao Jumiao). Regardless of whether they are viewed as coarse or subtle, and or neither coarse nor subtle, they all contain the ultimate intention of the Buddha in leading beings to attain Buddhahood.
