吐鲁番吐峪沟第42窟有并列禅观比丘壁画。这些壁画似乎与禅观经典有关，但其确切关系还不明显。第42窟的壁画内容与禅观经典文本的描述在一定程度上存在着一致性，而且不少成组的场面都能与文本的相关内容对应上，但就总体布局而言，这些画面却和当今所见的所有文本都不一致。所以其壁画作品未必是以某一经典为蓝本的，很有可能依据的是当地的禅观传统，壁画所依据的经典很可能是吐鲁番的地方产物。这个意见对学界长期争论不休的《观无量寿佛经》来源地的问题也有可能提供重要的着眼点。“,”Toyok cave 42 contains wall paintings of visualizing monks that seem to be associated with Chinese texts on meditation. The wall paintings accord with descriptions of meditation in the texts to a certain extent and corresponding depictions can be matched for some paired scenes, though the overall layout of these scenes is inconsistent with those found in texts available today. Therefore, the wall paintings are not necessarily based on a single sutra but likely come from local meditation traditions;indeed, the text the wall paintings are based on may have originated from Turfan. This explanation could provide key information on the origins of the Amitayus Visualization Sutra which has been in endless dispute.
