While the physical body is here and the vital force, some activity will be going on, some duality will be playing out. It is very important that these things come and take you out of your projected state. We still have a relationship with our mind, with our sense of identity, with how we want things to be and how we want to be perceived.
The stain of identity is one of the last ones to be removed. In Satsang this stain is dissolving, like ice in a glass of warm water.
