In the 1200s, when the Takaoka Daibutsu was enshrined on Mt. Nijo, it was a wooden Buddha. In the Edo period, when Maeda Toshinaga built Takaoka Castle, the Takaoka Daibutsu was also relocated. After that, it was burned down twice, and in 1932 it became the Buddha we see today.
Dainichi Nyorai is regarded as the highest Buddha in Esoteric Buddhism, and is considered to be the universe itself, the highest being. He is the Buddha equivalent to God in Christianity, Yehvah in Judaism, and Amaterasu Omikami in Shinto. A big difference between Christianity and Buddhism is that in Christianity, the highest being is the object of worship, while in Buddhism, this is not the case. In Takaoka, you can see various Buddhist statues, including the Great Buddha, and you get the feeling that they are peacefully worshipped.
In the Buddhist worldview, Tennin are gods who reside in heaven as physical entities. Therefore, they are said to have a lifespan and to live in the realm of desire (a world trapped by desire) or the realm of form (a world free from desire but still possessing color).
This painting represents the hell created by the human mind in the Buddhist worldview. In Christianity, it is believed that "those who don't believe in God will go to hell," but in Buddhism, it is considered to be "a world of suffering that we create ourselves." In other words, hell isn't a place that exists somewhere, but is our own state of mind. The Buddhist view is that all suffering, such as suffering from debt or hard labor, feeling depressed after a breakup, or feeling anxious because of illness, is created by our own minds.
In Buddhism, there is a traditional idea called impermanence, which states that all things arise from nothing and will return to nothingness. There are no waves that last forever or are perfect, and even waves at their peak disappear in an instant. Similarly, this painting expresses the idea that there is no such thing as "beauty" or "power" that lasts forever.
