East Asian Pilgrims like Faxian and Xuanzang recorded their own itin-erary including their accounts on Indian arts and Buddhism on their per-spective. Since a few images remained in India, their references to the Buddhist art in India are very helpful to explain the iconography in the transitional periods, This article investigates the pilgrims` understandings on the belief in Avalokitesvara and its images. According to Faxian zhuan, Faxian did not pay much attention to the Avalokitesvara sculpture. In his reference he was only concerned about the belief in Avalokitesvara, He thought Avalokitesvara as a savior of any man in peril, His understanding of AvalokiteSvara shows us his recognition of the same period. While Faxi-an didn`t mention any Avalokitesvara images in India, Xuanzang left some information on the Avalokitesvara images. In Datangxiyuji Xuanzang referred to several statues of Guanyin. However he mentioned few of their features. It means that the appearance of bodhisattva was no concern of his, Xuanzang was deeply impressed on the way which certain Avalokitesvara mages answered the prayer of buddhists. He believed jf a man prayed with whole heart for a long time, he would get Guanyin`s answer and be finally saved. On the other hand, Xuanzang disregarded the transformed images of Avalokitesvara like Lokesvara, Lokanatha, and Kasarpa a Lokesvara which had multiple arms and heads, These multiple armed and headed Avalokitesvara images appeared in late Gupta period under the influence of Hinduism. Even if Xuanzang had known these vari-ous transformed Avalokitesvara, he described only two-armed Avalokitesvara images with the lotus flower. He seems to think that only Padma-pani would be Avalokitesvara. Although Indian buddhists in Kushan period began to make the Avalokitesvara image with a lotus flower, after Gupta period it was changed. Multiple armed and headed Avalokitesvara images were increasingly created with two attendants of nra and Bhrkutl, Sometimes Indian buddhists adored Tara in eastern region of the country. Tara, the female deity, has utpala on her hand and under her knee Ashokakantha Maffci and Ekajata are represented, Although Tara is regarded as one of the other incarnations of Avalokitesvara, there is no reference whether Indian people believed the deity, Tara, as Avalokitesvara, Most scholars agree that the iconography of Avalokitesvara in India influenced to East A ia, But it is doubted that the esoteric Avalokitesvara images also influenced to East Asia.
