Neti Neti is a Sanskrit phrase that means "not this, not that." This phrase is used in Hindu philosophy to explain the way we think about the universe. Essentially, it means that the things we think we know and understand about the universe are not the full truth. Instead, we can keep looking deeper and learning more about the true nature of reality and our place in it. By looking beyond what we think we know, we can gain a greater understanding of our world.
