The new moon is a time have a fresh start, to begin new goals. It's a time to let go of old habits and old behaviours, even old beliefs and replace them. So this Black moonstone is very synchronistic to each new Moon because it provides a Place, a energy, a gift of introspection, intuition and even dreaming. WIthout a dream how can you have a dream come true?  

“ I do hereby declare that I'm using this sacred oil of black moonstone so that I accept my choice of a new start of the study through introspection and releasing old habits that I might be clear in the cleansing of great feminine energies. I ask the Divine feminine in all her forms, in all her names to guide me in this endeavor.  And it is so. “
