Feeling and opening your genuine heart of sadness is the key to letting go of your preconceptions and your interpretations of the world. By letting go, you leave your familiar and snug world behind, at least for a moment, and relax into the sacred and strange space of the real world. To do this, you need to have basic trust. Basic trust is not trusting in something but simply trusting. It is very much like breathing. You do not consciously hold on to your breath or trust in your breath, yet breathing is your very nature. When you breathe out, you trust that the next breath will come in---you don't think about it, or wonder about it, you trust. When you take a step, you trust that the earth will support you. When you eat, you trust that your stomach will digest the food. This is basic trust.
