摩訶止觀 1.138

1.138

分別十六門道滅不同及一切恒沙佛法，分別校計，不可說、不可說，如觀掌果無有僻謬，皆從心生，不餘處來。觀此一心能通不可說心；不可說心能通不可說法；不可說法能通不可說非心非法。觀一切心，亦復如是。

Discriminating the differences in the paths and cessations of the sixteen gates, as well as all Buddha-dharmas as numerous as the sands of the Ganges, discriminating and calculating ineffably, ineffably—like seeing a fruit in the palm of one's hand without any error—all arise from the mind and do not come from anywhere else. Contemplating this one mind can penetrate ineffable minds; ineffable minds can penetrate ineffable dharmas; ineffable dharmas can penetrate ineffable non-minds and non-dharmas. Contemplating all minds is also like this.
