Tathatva

Tathatva, in philosophical terms, refers to the fundamental reality or essence underlying all existence. It is the unchanging truth that remains constant beyond the surface appearances and diversity of the visible world. Think of it as the core principle that sustains everything—similar to how the concept of "water" is the essential nature of ice, vapor, and liquid. Recognizing Tathatva helps one understand the unity behind apparent differences, highlighting the interconnectedness and ultimate reality that underpins all phenomena in the universe.
