本文对新疆克孜尔石窟第17窟、123窟立佛背光中绘满许多小化佛的现象,以及对龟兹地区发现的两处卢舍那图像进行了分析考证,认为前者是小乘佛教法身思想在石窟内的表现,后者是公元8世纪后受到中原大乘佛教影响的结果。

龟兹中心柱石窟壁画内容主要是围绕释迦牟尼佛展开的,在具体表现方面主要由反映释迦前世行菩萨道时的事迹与成道后至涅槃之间的题材构成。很多壁画内容表现释迦牟尼在三阿僧祇劫中对大量过去佛的供养,体现了小乘说一切有部强调在成佛过程中必须"逢事诸佛"的思想,另外,公元6世纪后壁画中还出现了特别宣扬释迦神通力及降服外道的题材,这正是小乘佛教"唯礼释迦"观念的具体表现,与龟兹小乘说一切有部长期占据主流地位有密切关系。

龟兹回鹘风格的石窟是公元9世纪回鹘西迁龟兹后接受汉地文化而形成的,佛教教义方面受到龟兹佛教与安西大都护府时期来自中原佛教思想的影响,大乘佛教尤其是密教的影响较深,出现了地狱变的题材。另外,回鹘风格壁画与龟兹风格、汉风壁画在石窟中并存,反映了三种艺术风格在一个石窟中显现混合性的特点,证明了回鹘风格是在继承了当地龟兹风格、汉风壁画的基础上形成的,并具有回鹘民族自身的审美风尚。

公元4-5世纪是龟兹佛教的一个兴盛时期,具体表现在有很多著名的地面寺院的修建以及石窟的开凿,而且有些寺院在此之前就已经存在。石窟方面,尤其是大像窟的开凿,更使龟兹佛教艺术达到了一个高峰。另外,这一时期方形窟和中心柱窟都有开凿,而且在绘画上一开始就呈现出相当成熟的绘画技法,出现两种画风并存的局面。龟兹佛教的兴盛与末法思想在当地流行有关,由于贵霜王朝境内佛教的衰落,导致东来的高僧在龟兹停留并传播佛法。佛教得到龟兹王室的大力支持,国王以转轮王的角色出现,护持佛法。

新疆克孜尔石窟是龟兹石窟的重要组成部分,其独特的形制、丰富的壁画内容被称为“龟兹样式”,而以中心柱石窟最具代表性。壁画内容主要包括本生、因缘和佛传故事画等,这些壁画是围绕着释迦牟尼佛本身展开的,着重反映释迦牟尼前世本生、今生本行、最后涅槃的事迹,是小乘佛教“惟礼释迦”思想的具体反映。在新疆塔里木盆地北缘出土的佛经残卷,大多属于小乘说一切有部的经典,主要来源于小乘佛教经典“四阿含经”,说明这一地区小乘佛教占据主导地位。
