Going to sleep is a little like dying. We completely lose ourselves in a void for some period of time, until we arise again in a dream. When we do so, we may have a different identity and a different body. We may be in a strange place, with people we do not know, involved in baffling activities that may seem quite risky.

Most importantly, in dream the mind’s limitations can be challenged and overcome. As they are, we develop flexibility of mind, and this is most important. Why is flexibility of mind so important? Because the rigidities of mind, the limitations of wrong views that obscure wisdom and constrict experience, keep us ensnared in illusory identities and prevent us from finding freedom.
