Tankha are Tibetan and Nepali Buddhist artworks said to assist in the quest for liberation. The visual themes are almost always religious in some fashion. Wikipedia explains:
Thangka perform several different functions. Images of deities can be used as teaching tools when depicting the life (or lives) of the Buddha, describing historical events concerning important Lamas, or retelling myths associated with other deities. Devotional images act as the centerpiece during a ritual or ceremony and are often used as mediums through which one can offer prayers or make requests. Overall, and perhaps most importantly, religious art is used as a meditation tool to help bring one further down the path to enlightenment. ¹
Here are some examples:
From the above we can see the visual diversity of the Tankha. The Swiss psychologist C. G. Jung was particularly interested in their mandala qualities. Jung likened the tankha to circular shaped Christian art that he felt was pointing to the same, or a similar phenomenon—the self.
“I sketched every morning in a notebook a small circular drawing,…which seemed to correspond to my inner situation at the time….Only gradually did I discover what the mandala really is:…the Self, the wholeness of the personality, which if all goes well is harmonious.”—Carl Jung, Memories, Dreams, Reflections, pp 195 – 196.
The reason I say “similar” is because Jung, at some points in his Collected Works and Letters, argues that Christianity differs from Eastern religions. The upwardly skewed symbol of the cross, he felt, indicated an upward bias. Jung once said that Eastern yogis, lamas and saints were “at bottom” of the spiritual change we see in the West.²
