Ok, there are a lot of meditations that are around which are designed to balance your energy and to help clear the chakras. It just depends on how elaborate you want to get.
Oh, your throat chakra and the third chakra are the same thing.
One that I used for a long time, I found it in the book by David Pallidini that accompanies the Aquarian Tarot, goes like this: lie down, get comfortable, imagine your aura around you, and imagine that you have a pipe-like outlet that starts on the top left side of your head, though the your aura that leads outside of your energy field. Relax your body as completely as you can, go like a wet noodle.
Start with your base chakra, at the bottem of your spine, and feel the energy in it, and release any negative energy that you have collected in that chakra. Imagine that the negative energy, the black icky stuff flows up your body, though the pipe that you imagine in your aura above the left side of your head, outside of your energy field, that the negative black bad stuff flies up into the sky, and the sunlight/starlight/moonlight turns it into healing energy and it falls where ever it's needed to the earth.
then do the sacral chakra, located roughly in the genital area, clear it out, move up to the solar plexus chakra, clear it out, go up to your heart chakra, clear it out, do the throat, the thrid eye chakra (in the middle of your brow) and then do the crown chakra at the top of your head.
There are colors associated with the chakras, and you can visualize the black stuff leaving the chakra and seeing it as a clear color.
traditionally chakra colors are
People have several energy layers around them, I remember the explanation from the Aquarian Tarot was really detailed, but just imagine that you have several envelopes of energy around you, and make sure that any negative energy that you sense in any chakra gets out through the pipe, away from you forever, and changed by the sun or moon or stars.
I will either wear a charged crystal or a strand of turquoise when I have to be around people, it helps me act and speak more easily.
This is a good begining meditation, and will clear your energy of anything foriegn, and will allow you do to a good tarot reading because your energy will be refreshed and not influenced by your past baggage, or whatever you might have picked up from somebody else. When I did this meditation, I often remembered situations and people from my past where there was unresolved upset, and it helped get rid of it for me.
The thyroid is usually connected to the throat chakra, obviously Iodine
is a great help from a physical standpoint.
To be honest, I haven't been able to do a reading in months, it will be wonderful to feel well enough to be able to do more than just the stuff I have to do to keep my business going. I use a similar meditation now, that balances my energy but is a little harder to visualize. As you practice visulization you get better at it. Obviouly if our brains are using quantum space, what we think is going to affect us pretty dramatically, so the more disiplined we get at controlling out thought processes/emotions the better results we will have.
If you want to go furthur in this direction, there are a lot of books I can suggest.
