👉 Daeva is a concept in Japanese philosophy that refers to "the essence of reality" or "the ultimate reality." It was first introduced by the philosopher Yasutaka Teshigahara in 1962. Daeva is often associated with the idea of the ultimate reality, which is said to exist beyond the material world and is eternal, unchangeable, and without beginning or end. Daeva can be seen as a philosophical concept that challenges traditional notions of existence and reality.
