When the doors of your restaurant open, you should do so on a waxing, crescent, or full moon. You can always create, plan, and prepare your project on any part of the lunar cycle.
The moon relates to gestation and birth. When you conceive an idea, it is embryonic. When the fetus is ready for birth, the full power of the moon or lunar currents are present. This is why the opening of the restaurant (or project), should occur on a waxing, crescent, or full moon, since the project already formed in the darkness, obscurity, or womb of the mind, and is now ready for the light of manifestation.
For thirty years I sought God. But when I looked carefully I found that in reality God was the seeker and I the sought. -Bayazid al-Bastami
