After purchasing your crystal you will need to clean it. If you have a crystal that will not be damaged by water (ask your supplier) it can be held under a tap or immersed in salt water. You can also use a bag of brown rice or sea salt and leave them sitting in it overnight and some people use smudging (pass them through the light of a candle or visualize them surrounded by white light). This will clear away any negative energies and purify them. Next, allow them to sit in the light of the sun or full moon to re-energize them. Now you are ready to connect with them personally.
To begin you will need to activate your crystal. Hold it in your hands and imagine light all around it or hold it in front of a light source and then formulate your intention. Just be specific on how you want to use it.
This is what I used for my Apophyllite:
"To my highest guides and helpers second to none, bless me and protect me knowing that everything that is said, heard, felt or sensed is with absolute love. I wish to connect with this crystal and use it as a CLEAR CHANNEL to receive guidance and wisdom from my higher self."
I then sit and meditate holding the crystal for about 15 minutes in silence. When I am through I send a blessing and give thanks to all of the guides working on my behalf and I go on my way.
Try it for yourself and begin to use crystals in your meditations. Tap into their wondrous power. It is a gift worth giving yourself and may open new doors to the YOU that has been waiting for a visit:)
