Applied to the life of the individual, the Law of Periodicity manifests itself as follows:
Human life on the earth plane is divided into periods of seven years. The first seven years represent the period of infancy. With the next seven, the years of childhood, begins individual responsibility, the conscious discernment between right and wrong. The third group comprises the years of adolescence; the fourth marks the attainment of full growth. Nearly all civilized countries take cognizance of this fact by fixing the legal age at twenty-one.
The twenty-eighth year, the beginning of the fifth period, is another milestone along the road to development.
The sixth period, beginning at the age of thirty-five and ending at forty-two, is marked by reactions, changes and crises. It may, therefore, seem an unlucky period; but if we understand the law and comply with it, we shall be better and stronger in every way after we have passed this period.
During the seventh period, the effects of the sixth or crises period continue and adjust themselves. It is a period of reconstruction, of recuperation and rest, and thus the best preparation for a new cycle of sevens which begins with the fiftieth year.**
**Those who are interested in the Law of Periodicity as applied to life in general, will find much valuable information in a book entitled Periodicity by J. R. Buchanan, M.D., published by the Kosmos Publishing Co., 2112 Sherman Ave., Evanston, Il.
In this connection it is interesting to note that the Mosaic law recognized the law of periodicity and fixed upon Sunday as the first day or "birthday" of the week, and upon Saturday (the Sabbath) as the last or "rest" day, in which to prepare for another period of seven days.
Orthodox science now admits that the normal length of human life should be about one hundred and fifty years. This would constitute three cycles of forty-nine years each, the first corresponding to youth, the second to maturity, and the third to fruition.
