天台菩薩戒疏 2.18

2.18

第十四，放火燒戒。火性焚蕩，損物非輕也。既已非時，寧容故放，所以制犯。別具五緣：一、是山林，二、知是，三、起惡心罪，四、非開時，五、故放，便犯。就文為三：初、標名列過，次、「不得」下正制止惡，三、「若故燒」下違制結犯。初又二：初列無主物。初言「惡心」者，報酬、嫉財、畋獵等也。為護生命，有情無情此時興盛，故制時也。次「若燒」下列有主物，約損財邊，不論時節。二、三如文。

Fourteenth, the precept against setting fires to burn. The nature of fire is to incinerate and sweep away; its harm to things is not light. When it is already not the appropriate season, how could one permit setting it intentionally? Therefore an offense is instituted. It specifically comprises five conditions: first, being mountains and forests; second, knowing them to be such; third, the sin of giving rise to an evil mind; fourth, not being the permitted season; fifth, intentionally setting it; whereupon one commits an offense. The text has three parts: first, designating the name and listing the fault; next, from 'must not' onward, directly instituting the prohibition of evil; third, from 'if one intentionally burns' onward, concluding the offense for violating the institution. The first part also has two aspects: first, listing ownerless property. When it first says 'evil mind', it means vengeance, jealousy over wealth, hunting, and so forth. In order to protect life, sentient and insentient beings flourish at this time, which is why a season is instituted. Next, from 'if one burns' onward, it lists owned property, considered from the side of damaging property, without regard to season. The second and third are as in the text.
