Identification of the108 Forms
Fig.1 shows the arrangements of the 108 forms. The numbers from 1 to 108 in Fig.1 correspond with the numbers from 1 to 108 for the names in Table 1.
Table 1 shows the names of the 108 forms in Japanese and Sanskrit identified with the black and white drawings of 108 forms of "The Mikkyo Zuzo (The Journal of Buddhist Iconography) Vol.8 July 1990" (ISBN4-8318-0408) edited by The Association for the Study of Buddhist Iconography, Kyoto, Japan, the contributors to which are Musashi Tachikawa and Hidenobu Takaoka. Included also in Table 1 is the body color of each form followed by the names.
This reference is very helpful for identification, although there are some differences between the 108 black and white drawings and the 108 forms of the thangka, since they are similar enough to identify with great ease. The most noticeable difference is No.52 Sahasrabhujalokeshvara or 11-headed 1000-armed Avalokiteshvara. No.52 of Fig.1 is an eight-armed Avalokiteshvara with one face. Above the deity is Amitabha depicted red in color separately, thereby he looks like being floating. It is possible that the artist intentionally replaced the deity with the principal deity at the center of the mandala because of some kind of reasons.
