Since the harmful effect of the new and full moon is due to a spiritual reason, only spiritual remedies or spiritual practice can help in giving protection. At a worldly level, it is best to avoid taking important decisions or buying-selling on these days as ghosts can affect through these media. Increase the quantity and quality of spiritual practice from 2 days prior to and continue for 2 days after full moon and new moon days. It is also beneficial to chant Name of God as per religion and the spiritual protection chant of Sree Gurudev Datta. During the waning phase of the moon, i.e. the period between full moon day and new moon day, as the size of the moon progressively reduces, the subtle basicraja-tamafrequencies emanating from it progressively rise. This is because the darker side of the moon progressively increases. Hence to protect oneself from the adverse influence of this enhancedraja-tama, it is important that we step up our spiritual practice during this period. During the waxing phase of the moon, we should at least try to stabilise the increased efforts we had put in, in the earlier fortnight. This is so that we can again renew our efforts at enhanced spiritual practice in the next waning phase of the moon.
