" This is the work of a lifetime, here on earth: To invent the astral body, to create it. giving it our consciousness. Thus one will survive death. One could also die when one chooses… And on dying, not lose the awareness 'from here.'

What has happened to you is a detachment of your astral body while your physical body sleeps. This occurs to vîras; it's an automatic unconscious process. Sometimes, by simple chance, a glimmer of consciousness reaches this fine body and then, on suddenly awakening or the next day, one gets the impression of experiencing something much more real than physical reality. The deja-vu of psychologists has its explanation in this phenomena of detachment.

Have you seen those children who elevate a kite and send messages with little rolls of paper that go slowly up to the kite? So it is, more or less, with that other. The astral body breaks away, still attached to the physical body by a string which has been called a 'silver cord' that is only cut at death. Thanks to this cord we can go immeasurable distances without losing the connection with our physical bodies. It always returns. So it reaches consciousness, like those messages of children with their kite. Yes, we must become like children to enter into the Kingdom of Heaven… with our astral bodies. Pay attention to this other analogy: As a child finds itself joined to its mother by the umbilical cord, so the astral body is joined to its father, the physical body, by a silver cord. The child cries and despairs at birth, when the cord connecting him to his mother is cut. He thinks this is death, but it is a new life. The same befalls the vîra when he dies; when the silver cord is cut he enters into another life. Death is a new life. All this is archetypal. Only those events expressing archetypes have ontological reality. "
