When talking about the Living Inquiries, I tend to avoid the “unfindable” terminology since it easily can be misunderstood.
People may get caught in thoughts such as “if it’s unfindable, doesn’t that mean it doesn’t exist?”, and may even scare themselves unnecessarily through that way of thinking.
Instead, I often say:
Through the inquiries, I get to see how my mind creates my experience of X. And after an inquiry, there is often a sense of lightness around it, and less stickiness and drama. (It’s not about whether something exists or not “in itself”. That’s another topic, and not really relevant or important.)
