●○△□ means... Zen painting is "Kaiga Muho" Zen painting
It is a simple drawing that only depicts the shapes "circle", "triangle", and "square", and on the left edge is only the seal that is said to have been drawn by Sengai of Shofukuji Temple, "Fuso First Zen Cave (the oldest Zen temple in Japan)".
○ (Enso)
Everything that exists in the universe, the universe itself (absolute truth)

△ (Zen sitting posture)
The figure of a person who is one with the Buddha while sitting in meditation with his legs crossed

□ (Captive mind)
We live surrounded by the square of social norms

Color (things with form) are no different from the sky; the world of tangible things consists of triangles and squares.
When you fold a square in half, it becomes a triangle, and you can continue folding it as a triangle.
*This painting on a tea bowl is meant to offer a window into the deeper realm of Zen.
