Zurvanism/Ages of Man
Thus it is ordained by the Wise Lord that the ages of man shall be marked by the bane of mortality. Let it ever be thus!At fifty years of age, the bane of mankind claims the soul after a short life. May those without progeny perish before this time.
At sixty years of age, the soul has attained maturity worthy of its flesh. May the soul without courage perish before this time.
At seventy years of age, the soul has attained a sufficient life. May the soul without wisdom perish before this time.
At eighty years of age, the flesh will have enjoyed the fruits of old age. May the soul part from the flesh with contentment before this time.
At ninety years of age, the soul shall have known the decrepitude of the flesh. May the soul pray for the mercy of deliverance from a corrupted world before this time.
And all shall be in accordance with the will of Highest Divinity.
