February 6. On this date in 1973, the Universal House of Justice wrote "Just as there are laws governing our physical lives, requiring that we must supply our bodies with certain foods, maintain them within a certain range of temperatures, and so forth, if we wish to avoid physical disabilities, so also there are laws governing our spiritual lives. These laws are revealed to mankind in each age by the Manifestation of God, and obedience to them is of vital importance if each human being, and mankind in general, is to develop properly and harmoniously. Moreover, these various aspects are interdependent. If an individual violates the spiritual laws for his own development, he will cause injury not only to himself but to the society in which he lives. Similarly, the condition of society has a direct effect on the individuals who must live within it."

1146. Laws Governing Physical and Spiritual Lives
"Just as there are laws governing our physical lives, requiring that we must supply our bodies with certain foods, maintain them within a certain range of temperatures, and so forth, if we wish to avoid physical disabilities, so also there are laws governing our spiritual lives. These laws are revealed to mankind in each age by the Manifestation of God, and obedience to them is of vital importance if each human being, and mankind in general, is to develop properly and harmoniously.
