Buddha mandala is an art either made out of sand or a painting. It is used as a visual aid for concentration and healing purposes. It is used in meditation halls too. In the painting, there are many smaller circles inside a big circle. In the radial lines of the circle, we can see tiny pictures of Buddha. Above all, the painting tries to reveal the Buddha in different forms.
There are many types and varieties of Mandalas depending on the nature of the central deity. The most classic pattern of Mandalas is of the Dhyani Buddha. This Thangka depicts Buddha Mandala. The Mandala represents “palace of purity” a magic sphere cleared of spiritual obstacles and unpurified. The square of the “Sacred palace” proper is end used in multiple circles of flame, Vajra, eight centuries (appears only in wrathful deities) lotus, then the inner square to reach to the deity of the Mandala.
Amitabha, (Sanskrit: “Infinite Light”) also called Amitayus (“Infinite Life”), Japanese Amida, Chinese Emituo Fo, in Mahayana Buddhism, and particularly in the so-called Pure Land sects, the great saviour buddha. As related in the Sukhavati-vyuha-sutras (the fundamental scriptures of the Pure Land sects), many ages ago a monk named Dharmakara made a number of vows, the 18th of which promised that, on his attaining Buddhahood, all who had faith in him and who called upon his name would be reborn in his paradise and would reside there in bliss until they had attained enlightenment. Having accomplished his vows, Dharmakara reigned as the buddha Amitabha in the Western Paradise, called Sukhavati, the Pure Land.
