Quartz can be either active or passive, Yin/Yang. If you are looking for more of a receptive energy with your Tarot deck, keep a milky Quartz in the container or box you store your cards. If you are looking to infuse a more active energy, go with a clear Quartz. Same goes for when you are using the Tarot for yourself or others. Keep those crystal's near by to further activate the desired energies in your psyche. You can also check into many other types of crystal's such as Lapis Lazuli, Obsidian, Onyx, Amethyst etc... If you are into Herb's, or Feng-Shui and space clearing, you can also clear the area with your favorite herb before and after you use the Tarot. You may also enjoy using a bell before or after, just to clear the air. There are so many different thing's you can do, from yoga, meditation, prayer, even just simple candle burning can help induce a positive atmosphere and clear away the residue left behind after a deep session. You don't have to do any of this, but I guarantee that if you do, you will reach a deeper understanding of yourself and your surroundings. Then one day out of the blue you will realize that you have come to a point in your life that you can activate these feeling's and vibrations without needing anything but your own mind and will.
All these ancient techniques such as burning sage and incense, using crystals and other elements to guide your will, all these techniques are sacred because they reach deep into your unconscious, the primitive aspect of all human existence. They tap into those memories of use by other ancient people for various spiritual reasons. Bringing great force and power from the memories of all your great ancestors and that of many different cultures and traditions. Just you think of essential oil's for a minute, that is the Chi, or life force of the plant, the energy. Burning the oil is releasing it's energy into the atmosphere, you are then able to embrace the plants whole existence and reach strong memories from the past that you cannot activate any other way. Ancient cultures also enjoyed burning incense due to the thought that the smoke would carry their prayers to the heavens. This is still done today. Just remember to keep your intentions pure before lighting the incense and before storing your cards with crystal's. Your thoughts really do matter, for your reality is only as real as your imagination.
Where you store your cards is very important as well, make it a spot that is sacred to you or a spot that at least has some special importance to you. That act alone will charge the card's with positive energy for future sessions. If you just experiment with what feels most natural to you, you will figure out what best resonates with your true intention and intuition.
Please don't believe a word I say until you see the evidence in your own life. You must experiment for yourself and see what truth you can discover in your own unique way.
Good luck and don't forget to have fun playing Tarot!!!
Sincerely,
