In this outer evolution of the living being's organism from mineral to plant, animal and human being we see the cosmic formation of an embryo. From having no particular faculty to experience, the being reaches a point where it can experience and create one hundred per cent perfectly both spiritually and physically, this result being the fulfilment of the conditions for being able to experience the very highest happiness or the very culmination of the experience of life. As the being, at the beginning of a spiral cycle, thus begins to unite with physical matter, and little by little quite automatically develops its physical organism with which it can begin to experience and create in physical matter, it, by virtue of this experience, comes under the law of life for perfect experience and creation. This determines that this creation absolutely must be logical, whether it be a matter of behaviour or any sort of creation in physical matter itself. Where this does not occur, the experience of life becomes catastrophic.
