People who know how to use the phases of the moon have better chance of success in all they undertake, whether material or spiritual. The period of the waxing moon favours all natural growth; so according to the law of analogy that governs the universe, we must always choose this period if we want to construct something, or begin an important project in our lives. If we work according to the phases of the moon, this divine law goes into action. The plan itself can be drawn up at any time, but once it has been decided to go ahead, the work of realization must begin during the waxing moon. And if you want to bring some venture to a close, it is better to do so when the moon is waning. The moon is linked to material achievement, whether it be the beginning or the ending.
