首楞嚴義疏注經 9.88

9.88

This is the heading. 'Existence' is precisely form; 'Summit' is the ultimate. Form halting here is called the 'boundary of form'. The 'two divergent paths' are: first, the path out of the three realms, which is tread by those who turn their minds; second, the path entering the formless, which is trodden by those of determinate nature. If they are ordinary persons or non-Buddhists, since they do not enter these five heavens, they enter instead from the two heavens of Vast Results and No Thought, not being within the limits of what these two tread. This will be understood below on its own.
