Celestite is perfect for meditation as it is a calming stone that gives healing energy. This stone also enhances the Throat Chakra and aids in communication.
Crystals come into contact and can hold energy and intent from others (hands) so here are ways to clear/cleanse & activate your stone.
To cleanse:. Smudge with smoke and speak intentionally over it. Visualize white light pouring out over your crystals and ask Spirit to dispel all negative energy that doesn't serve you.
To activate/program: Speak the desired intentions over your stone. "I speak/pray the intention of ______ over this crystal for my highest good." Wear the crystal close to your body to connect with it.
