"Begin the mantra when the Moon in its full phase, is strong in its home sign of Cancer, or when it is in its exalted sign of Taurus. The Moon is at its most powerful when it is full. DO NOT begin this mantra when the Moon is in the signs of Scorpio [its fall] or Capricorn [its detriment]. Begin the mantra on a Monday, during the hours of the M oon. Begin during night hours, when the Sun is completely set and it is dark, and the Moon is visible, the brighter the Moon, the better." ( JOS 14) It all matters when you BEGIN it. Preferably a full moon, begin on a Monday, and check to see where the Moon is on that Monday. When you're finally in the working you don't need to worry about anything else other than doing the amount of Mantras per day.
