Mandala is a circle which is a device for the Tantric meditation. It is a visual aid for concentration and introversive meditation leading to the attainment of insights and to activation of forces culminating in “Siddhi” supernatural forces. The Mandala is the graphic representation of this process. It is not only theoretical but practical also as an operational scheme involving a clear plan for the practical realization of the process within oneself. It thus becomes an instrument (Yantra). There are many types and varieties of Mandalas depending on the nature of the central deity. The most classic pattern of Mandalas is 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 users 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.
