Budhakṣetra，剎者土之義，佛剎者佛土佛國也。大乘義章十九曰：「剎，是其天竺人語，此方無翻，蓋乃處處之別名也。」慧苑音義上曰：「剎，具正云紇差怛羅，此曰土田也。」
buddhakṣetra. 佛紇差怛羅 Buddha realm, land or country; see also 佛土, 佛國. The term is absent from Hīnayāna. In Mahāyāna it is the spiritual realm acquired by one who reaches perfect enlightenment, where he instructs all beings born there, preparing them for enlightenment. In the schools where Mahāyāna adopted an Ādi-Buddha, these realms or Buddha-fields interpenetrated each other, since they were coexistent with the universe. There are two classes of Buddhakṣetra: (1) in the Vairocana Schools, regarded as the regions of progress for the righteous after death; (2) in the Amitābha Schools, regarded as the Pure Land; v. McGovern, A Manual of Buddhist Philosophy, pp. 70-2.
一佛剎 其義有二，即：(一)指佛所住之國土。又作佛國土、淨土。(二)泛指一般寺院之堂宇。即佛塔、佛閣、佛龕、僧剎、伽藍等，專供修行辦道之處所。〔無量壽經卷上〕（參閱「淨土」5895）p3320
