Symbol 17
A Summary Explanation of Symbol No. 17 - Reincarnation, Cycles and Seasons
The symbol symbolises the various occurrences of the principle of the cycle. The four sub-principles that we know as the seasons of the year form parts of this principle. Winter is the epoch of darkness and coldness, where life or Nature manifests itself minimally. Spring brings light and warmth, making all life in Nature begin to bud and grow. In the summer, light and warmth culminate as life manifests itself to the full. In the autumn, light and warmth decrease, thus reducing the manifestation of life. Then winter returns. The same four principles of the seasons can be seen in the twenty-four-hour cycle, in the cycle of terrestrial life and in the cosmic spiral cycle.
