Fuhenteki
Fuhenteki is a Japanese term that translates to "unchanging" or "eternal." It is often used in a philosophical or spiritual context to describe a state of being that is constant and beyond the influence of time or circumstance. In Buddhism, for instance, the concept of fuhenteki can refer to the ultimate reality or the enlightened state, which is seen as permanent and unaffected by the impermanence of the phenomenal world. This unchanging nature is a fundamental aspect of Buddhist teachings on the true self and the nature of existence.
Beyond religious and philosophical discourse, fuhenteki can also describe qualities or characteristics that are inherently stable
