If you meditate on lead or some similar metal and again concentrate on its substantiality and metallity, you relinquish the body completely. You are left in no doubt that your physical body and etheric body are left behind on Earth. They appear strange and remote. They concern you as little as the stone concerns the rock on which it rests. Consciousness has left the body through the crown (the sagittal suture) of the head. Wherever we turn, a minute quantity, a tincture of lead is always to be found in the universe. This form of consciousness reaches far out into space; with the consciousness that is centred in the cranium man always remains in a state of complete insensibility. (Steiner 2010:24)
Meditation on Lead. We leave our body completely and rise to the Saturn sphere. (Steiner 2010:6)
