The soul's happiness comes when it is freed from its physical burden; it can only be happy when it can be itself. As long as man thinks he is his body, so long is he mortal, being only conscious of his mortal existence. But this, intellectually understood, will not help. The soul must see itself, the soul must realize itself. How does the soul do this? In the scriptures it is said, "Die before death." What is this dying? This dying is playing at death. The mystics have all through their life on earth practiced playing at death; by playing at it they were able to see what death is. Then it was not only intellectual knowledge; they actually saw that the soul stands independently of this physical garb. Buddha has called it Jnana, which means realization. The absence of it is called Ajnana, the lack of realization.
