In the Peruvian tradition we speak of the fifth sun, symbol for the place where enlightened souls and guides can be reached.
This place can be seen as a layer in the Upper World - a spiritual abode - but also as a layer in our consciousness: the enlightened version of ourselves. You can learn to cast your line, as it were, to this layer of consciousness to integrate it into your life. The sun can remind you of this. The sun brings light and warmth to the earth. As a human being, you can be a reflection of this: light and loving. When the sun shines, we also see our shadow. This shows: as a human being, enlightenment is always temporary. You are here as a soul in a body to learn. Even if you do not believe in souls, I am convinced that this inquisitive mentality leads to a beautiful and interesting life. There is always another lesson. This can be a trigger, a fear or a positive shadow: a beautiful side of yourself that you did not dare to see yet. Each time something comes up that you may integrate. This requires awareness. In Eastern medicine we call this Shen. Consciousness is so important because without it the lessons are not learned. The nectar of life is not tasted either. Life becomes dull and predictable. The sun shows us the light and the shadow again and again. It accompanies us on our journey and shows us the way. Like an honest friend who says: "There is light and yes, there is also shadow. But I do not shine any less because of it. I accept you completely."
