Yes, you should cleanse and recharge your crystals regularly to maintain their optimal energy and effectiveness. Crystals can absorb various energies from their environment, including both positive and negative vibrations. So, cleansing helps remove any accumulated or stagnant energies that would otherwise block you from attracting your soulmate.
To ensure that you’re cleansing and using your crystals properly, you can contact a psychic for a second opinion. You can always ask them to do a remote cleansing and programming of your crystals to boost their manifestation power. An experienced energy worker like a psychic can be a complementary tool to help attract your soulmate.
