Here, ten mandalas are arranged in an imaginative fashion, with a larger central one incorporating five smaller ones and four more surrounding the central mandala.
Each mandala has its own resident deity housed in the square structure situated concentrically within these circles. The perfect square shape indicates that the absolute space of wisdom is without aberration. This square structure has four elaborate gates. These four doors symbolize the bringing together of the four boundless thoughts namely - loving kindness, compassion, sympathy, and equanimity. This square form defines the architecture of the mandala described as a four-sided palace or temple. A palace because it is the residence of the presiding deity of the mandala, a temple because it contains the essence of the Buddha.
Interestingly, the centre-most mandala here shares its resident deity with the largest mandala circumscribing it. All ten depict Gautam Buddha in the Dharmachakra mudra. Dharmachakra in Sanskrit means the 'Wheel of Dharma'. This mudra symbolizes one of the most important moments in the life of Buddha, the occasion when he preached to his companions the first sermon after his Enlightenment in the Deer Park at Sarnath. It thus denotes the setting into motion of the Wheel of the teaching of the Dharma. This mudra is an idealization of the central function of the Buddha as a teacher, without which there would have been no Buddhism, and no path to enlightenment open before us.
Thus, meditating on this mandala will serve as a facilitator in transforming our ignorance into enlightening wisdom. Indeed, the Dharmachakra mudra is specifically believed to achieve this purpose.
