Truth is, we never bring our real and inmost Ego with us from the spiritual world into the physical and earthly; we leave it in the spiritual world. Before we came down into earthly life it was in the spiritual world, and it is there again between our falling asleep and our awakening. It stays there always, and if by day — in the present form of human consciousness — we call ourselves an ‘I,’ this word is but an indication of something which is not here in the physical world at all; it only has its picture in this world.
We do not see ourselves aright if we say: ‘Here am I, this robust and real man, standing upon Earth; here am I with my inmost being.’ We only see ourselves aright if we say: ‘Our true being is in the spiritual world, and what is here of us on Earth is but a picture — an image of our true being.’ It is entirely true if we regard what is here on Earth, not as the real man himself, but as the picture of the real man.
