The criterion that distinguishes
a school as Buddhist is its acceptance
of four fundamental tenets, known as
the four seals. These are: (i) all composite
phenomena are impermanent;
(ii) all contaminated things and events are
unsatisfactory; (iii) all phenomena are
empty and selfless; and (iv) nirvana is
true peace.
對於四個基本教義 -四法印- 的體認,
是分辨佛教流派的標準,
這些是: (i) 所有混成現象都是短暫的;
(ii) 所有受污染的事物和事件都無法令人滿意;
(iii)所有的現象都是空無, 沒有自我的;
(iv) 涅槃是真正的和平.
