法華經中所說之法也。光宅謂妙法者，一乘之因一乘之果也，前十四品說一乘之因，後十四品為一乘之果。一乘之因果，對於三乘之麤法而謂為妙法。蓮華者譬也，蓮華必華實同時而存，以表一乘之因果為同時也。天台謂妙法者，十界十如權實之法也。九界之十如為權。佛界之十如為實。此權實之法，悉為實相，而即空即假即中，故曰妙。蓮華者，譬此權實之關係也。何則？華如權法，實如實法，佛成道後至今時說權法者，是為欲說今之實法之方便，猶如華之為實而開。此謂之為實施權。次說明今日前所說之權法，悉為方便，顯一乘之實法者，猶如華開而實現。此謂之華開蓮現。次一乘之實法顯了，則實法之外無權法，權法悉為實，猶如實成而華落，此謂之華落蓮成。如此以蓮華表權實之施開發也。慈恩謂妙法者，一乘之因果，蓮華有出水開敷二義，以出水之義表所詮之理，超出二乘之泥水，以開敷之義表能詮之教能開真理。是依天親法華論之義也。嘉祥謂妙法者一乘法也。蓮華有十六種義，此中該收諸師之義。法華光宅疏一曰：「因果兩法俱稱為妙法蓮華者，外譬一物必花實俱有。」法華玄義一曰：「所言妙者，名不可思議也。所言法者，十界十如權實之法也。蓮華譬權實法也，（中略）蓮華多奇，為蓮故華。華實具足，可喻即實而權。又華開蓮現，可喻即權而實。又華落蓮成，蓮成亦落，可喻非權非實。如是等種種義故，便以蓮華喻於妙法也。」法華玄贊一曰：「蓮華有二義：一出水義，所詮之理出離二乘泥濁水故。二開敷義，以勝教言開真理故。前為理教，後為教妙。」法華玄論二曰：「問：以何義故，取蓮華喻此經耶？答：略明十種義。」
法華 The wonderful truth as found in the Lotus Sutra. the One Vehicle Sutra; which is said to contain 實法 Buddha's complete truth as compared with his previous 權法 or 方便法, i.e. partial, or expedient teaching, but both are included in this perfect truth. The sutra is the Saddhamapuṇḍarīka 正法華經 or (添品妙法蓮華經) 妙法蓮華經, also known as 薩曇芥陀利經, of which several translations in whole or part were made from Sanskrit into Chinese, the most popular being by Kumārajīva. It was the special classic of the Tiantai school, which is sometimes known as the 蓮宗 Lotus school, and it profoundly influenced Buddhist doctrine in China, Japan, and Tibet. The commentaries and treatises on it are very numerous; two by Chih-i 智顗 of the Tiantai school being the妙法蓮華經文句 and the 玄義.
經名，簡稱法華經，以蓮華的明淨來形容大法的微妙。
