觀無量壽佛經疏 3.110

3.110

九、從此想成時下，至遍滿彼國已來，正明結成上多身觀，生後說法相。此明諸行者等，行住坐臥，常緣彼國一切寶樹、一切寶樓華池等，若禮念，若觀想，常作此解也。

Ninth, from "When this visualization is accomplished" down to "filling that land everywhere," it properly explains concluding the above contemplation of multiple bodies and giving rise to the subsequent characteristics of expounding the Dharma. This explains that practitioners, whether walking, standing, sitting, or lying down, should constantly fix their attention on all the jeweled trees, all the jeweled towers, flower ponds, and so forth of that land; whether worshipping and recollecting, or contemplating and visualizing, they should constantly maintain this understanding.
