弥勒信仰流行于西域龟兹。克孜尔第 114 窟主室正壁龛内绘一身坐姿弥勒菩萨像，以弥勒为洞窟主尊，标志着弥勒信仰在龟兹地区达到了高峰。本文考证此窟主室前壁门上方半圆面故事为“十六婆罗门访佛”，这是释迦时代弥勒皈依的故事，和主尊弥勒相呼应。同时，主室券顶满绘菱格本生故事画，门道两侧上方各绘一幅誓愿图，本生和誓愿主题刻绘加强了菩萨道修行的氛围。本窟主室以弥勒为主尊，统摄了“菩萨行”的主题。前人推断克孜尔第 112 ～ 115 窟为龟兹的一座尼寺。因此，本窟的设计者和修行者应为一个崇奉弥勒并具有成佛之追求的龟兹比丘尼团体。 

Maitreya worship was prevalent in Kucha, in the Western Regions. In the Cave 114 of Kizil Grottoes, a sitting Maitreya Bodhisattva is painted on the main wall of the main chamber, marking the peak of Maitreya 
worship at the Kizil Grottoes. This paper identifies the narrative depicted on the semicircular surface above the 
door on the front wall as Sixteen Brahmins Visiting the Buddha, which recounts Maitreya’s conversion in the time of Sakyamuni. Additionally, the diamond-shaped Jātaka narratives on the vaulted ceiling of the main chamber and Praṇidhāna illustrations painted above each side of the entrance passage together enhance the atmosphere of bodhisattva-path cultivation. The main chamber of the cave, with Maitreya as the principal figure, focuses on the theme of the bodhisattva path. Previous studies have inferred that Cave 112-115 constituted a Buddhist nunnery in ancient Kucha. Therefore, the designers and practitioners of this cave should belong to a community of Kucha Bhikṣuṇī who revered Maitreya and pursued Buddhahood.
