You are capable of joy that has no explanation, no reason at all except that it is. This is part of the mystery of human Creation, and it’s why it’s good to know that the whole universe lives inside of you, not just your thought process. The whole universe of Divine consciousness lives inside of you.
Much of the movement of healing has to do with the shift from experiencing our thoughts as a way of going through the day, and experiencing life. And life is both inner and outer. It’s the dance, the dance of Creation, and it’s going on all the time. Only we don’t have the space, very often, to notice it.
