Then, in place of the physical body he beholds, not an empty space, but the etheric body. This body somewhat resembles the physical body and yet it is different. It takes on the form of the physical body, extending slightly beyond it. The etheric body is more or less luminous and fluidic. Instead of organs there are currents of diverse colours, the heart being a veritable vortex of forces and streaming currents.
Man possesses it in common with the plants.
In the plant, as well as in man, it is the force of growth, rhythm and reproduction. The astral body has neither the form of the etheric nor of the physical body. It is an ovoid and extends beyond the body like a cloud, an aura. The astral body can take on all the colours of the rainbow, according to the passion by which it is animated. Each passion has its astral colour.
