摩訶止觀 8.82

8.82

又觀僻動四大者：若觀境不定，或緣此，或緣彼，心即成諍；諍故亂風起，成風病。如御嬰兒行，但任之而已，急牽望速達，即為患也。又專專守一境，起希望心報，風熱勢不盡，成熱病。又觀境心生時謂滅、滅時謂生，心相違致痒痛，成地病。又不味所觀境而強為之，水大增，成水病。

Furthermore, when one-sided contemplation stirs the four great elements: if the object of contemplation is unstable, now attending to this, now attending to that, the mind falls into contention; because of contention, chaotic wind arises and produces wind disease. It is like guiding an infant to walk: one must simply let it take its course; if one pulls urgently hoping for quick arrival, it becomes an affliction. Moreover, if one single-mindedly clings to a single object, giving rise to the retribution of a hopeful mind, the force of wind and heat is not exhausted, producing heat disease. Further, when the object of contemplation arises, if the mind regards it as ceasing, or when it ceases, regards it as arising, the mind's conflict causes itching and pain, producing earth disease. Further, if one does not savor the object of contemplation but forces oneself to do it, the water element increases, producing water disease.
