The primrose-quartz spirit bottles can be used to unlock doors to other realms in your meditative/spiritual/mental/shamanic/magical work. Whatever type of work you do, from astral projections to vision traveling, primrose is a good ally to have if you come to a portal or a door that is locked. The plant works especially well with portals in nature and working with the Earth element. Quartz crystal is always a good choice to combine with any herb. It compliments primrose in these bottles in a lovely and very natural way.
