摩訶止觀 1.52

1.52

若其心念念專貪瞋癡，攝之不還、拔之不出，日增月甚，起上品十惡如五扇提羅者，此發地獄心、行火途道。

If in thought after thought one's mind is devoted exclusively to greed, anger, and delusion, unrestrained and unretrieved, uprooted and unextricated, increasing day by day and worsening month by month, giving rise to the superior grade of the ten unwholesome actions like the five kinds of caṇḍālas, this is generating the hellish mind and traversing the fiery path.
