The seven sacred planets (the five visible planets plus the Sun and Moon) relate to the days of the week and also planetary hours within days and seven sacred planets were associated with ancient Gods and Goddesses. The use then of these planets and their hours has an ancient history in Witchcraft and Paganism. These incenses help invoke the powers and characteristics of the individual planetary power. You can use these incenses to help convey the power of the deities represented by the Planets. They may also be combined with Zodiacal Incenses when one is working an astrologically-based spell.
