觀無量壽佛經疏 1.23

1.23

第十二普觀。普雜何異而為二耶？普觀作自身往想，稱彼境界一一具觀。雜觀明佛菩薩神力自在，轉變非恒、大小不定，或隨物現，故名為雜。以此為別。普中有二：初、從「見此事時當起自心」下，作自身往想。次、「無量壽佛化身」下，佛及菩薩化身來現也。

Twelfth, the universal contemplation. How do the universal and the miscellaneous differ so as to make two? In the universal contemplation, one forms the thought of oneself going there, and contemplates everything completely in accordance with that realm. The miscellaneous contemplation explains that the spiritual power of the Buddhas and bodhisattvas is sovereign, their transformations are not constant, their size is indefinite, and they appear in response to beings; therefore it is named 'miscellaneous.' This constitutes the distinction. In the universal contemplation there are two parts: First, from 'When seeing this matter, one should give rise from one's own mind' onward, forming the thought of going there oneself. Next, from 'Amitāyus's transformation body' onward, the transformation bodies of the Buddha and bodhisattvas coming to appear.
