When we first seek the truth, we think we are far from it. When we discover that the truth is already in us, we are all at once our original self. If we watch the shore from a boat, it seems that the shore is moving. But when we watch the boat directly, we know it is the boat that is moving. If we look at the world with a deluded body and mind, we will think that our self is permanent. But if we practice correctly and return to our true self, we will realize that nothing is permanent.
