22.255

三界焚如苦無量（周易卦九四注云其炎始盛故曰焚如今此言三界諸惑如火熾盛能招感多苦果故也）。

The three realms blaze, and their suffering is limitless (sanjie fen ru ku wuliang; the commentary on the nine-in-the-fourth line of the Yijing says: 'Its blaze begins to flare up, hence it is said to be fen ru.' Here it means that all afflictions of the three realms blaze fiercely like fire, being capable of bringing about many painful results).
