We take the fleeting objects of our perception to be solid & persistent – even eternal, and we build our identity based on these beliefs. This illusion can work for a while, but at some point when we find that the ‘solid’ ground we walk is not so solid after all, we tend to hold on for fear of losing our identity, and in that we suffer.
The belief that anything was ever solid was build on unexplored assumptions. Explore and recognise that at the heart of you, there is an emptiness from which all that you perceive arises.
