Many people are searching at this time, for what they call the truth. They are seeking guidance in this arena from "higher" beings on other dimensions. Well, surprise, you are one of these beings. Everyone has a Higher Self, that exists simultaneously on this dimension, as well as all others. The possibilities for life are limitless, and the great Spirit that you are wants to experience all the possibilities. You always have contact with your Higher Self, but it comes through more clearly when you focus your intent upon bringing Spirit into your life. So the phenomenon of channeling is really a simple concept: it is bringing in Spirit (not necessarily your own) and letting it communicate either to you or through you. Since your Higher Self is not limited by time or space, you can access the whole of your entire being, that is, your past, present, and future selves, as well as all aspects of it. Your Spirit is really greater and much more vast than you can imagine, because you are here on the physical plane, learning all about limitation, and don't have the "bird's eye view" that your multidimensional Self does.

Here is a simple technique you can use to channel your Higher Self, or Spirit. It is a very flexible method and you can always modify any of it to suit your own needs. Really anyone can do this.

Go somewhere that is quiet where you won't be disturbed, and where you can sit comfortably with your feet flat on the floor or ground, and your eyes closed. It may be helpful to keep a pen and paper handy to write your experiences as they go along. If you like, you can have a helper with you who can guide you through the initial meditation and ask questions of your Higher Self, and write your answers for you.

Grounding:
Take three deep breaths, letting yourself relax. Imagine your consciousness drifting down into the Earth, as you keep breathing slowly and deeply, and then your consciousness comes to rest somewhere inside the Earth, where you find a place with a certain mineral in it that you feel attracted to. See this mineral start to glow, becoming brighter with colored light, whatever color you like. Now see the light become a beam, and it is moving up now, all the way up until it enters the bottom of your right foot. Then become aware of your right foot, how it feels, and see the light begin to move up your right leg, and become aware of your right leg. Then, see the light continue to go up your right side, as you become aware of that area, then it enters your right hand, and continues up your right arm to the shoulder. Become fully aware of your whole right side, and see the light illuminating the whole right side of your body. Now move the light cord over to your left shoulder, and become aware of that area. Now the light begins moving down your left arm, hand, fingers, and you feel it moving down your left side, as you focus your awareness to your left side. Then the light cord moves down your left leg, into your left foot. Become fully aware of all sensations in the whole left side of your body. The light finally continues back down into the Earth, where it connects back to its source, completing the circuit. The light is continually in motion, moving up form the Earth up your right side as you breathe in, and circulating back down your left side and back to its source as you breathe out. Feel this energy revitalizing you as you breathe and relax.
Clearing:
Now see a third energy cord come up out of the Earth, perhaps of another color, and it enters your body at the base of your spine, the first chakra. See that chakra as a wheel of light, which fills up with this new energy and begins to glow brightly, and starts to spin. As it does this, any negative energies, fears, or blockages begin to clear out, and you see it spinning in perfect alignment with the your spine as an axle. See the top of the first chakra open up, and see the energy beam move up into the second chakra. Continue moving the beam up into each successive chakra, seeing each one clear out and start to spin, all the way up to the seventh chakra at the crown of your head. Then see the energy beam shoot up out of the top of your head, showering your whole body with light, which surrounds and protects you from any unwanted energies.
Enter your Sanctuary:
See your consciousness rise up along with the beam out through your crown chakra, and find a place for your consciousness to come to rest, anyplace that you like. First you see a doorway, and only you have the key to enter this place, your Sanctuary. Your sanctuary will only have the things in it that you allow. It can be in nature, a special room, another world, wherever you feel comfortable and safe. Now look around you. Off to the left, there is a fountain with a pool of crystal clear water. You go over to the fountain and peer into the pool. At first your reflection in the surface of the water is clear, but then you see the water begin to get wavy and from the center of the pool you see a magnificent being rise up out of the water, glowing in white light. It's your Higher Self, greeting you with unconditional love and acceptance. You greet your Higher Self, and together you go to another part of your Sanctuary, where there is a place for you to put your mind into a soundproof container, where it will stay for the duration of the experience. Notice how you feel about your mind. Know that you are safe and protected, and with you mind put away, you will be able to more fully experience your Higher Self without any judgment. Feel yourself merge into your Higher Self. The energy there is wonderful.
Return to your body with your Higher Self:
You and your Higher Self now leave your Sanctuary and find the bright beam of light that brought you here, and follow the beam back to your physical plane body, where you enter with your Higher Self through the crown chakra. Take a few deep breaths. Notice how you feel. When you feel ready, open your eyes. If you have a helper with you, now is the time to begin asking the questions you prepared for your Higher Self. If you have just written the questions down and have no one to help you, ask yourself the questions and just let yourself receive whatever thoughts, feelings, images, or other sensations come to you. Write down whatever it is that you get. Do not try to analyze now, there will be time for that later. Just let yourself flow with the experience. After each answer (whatever form that comes to you in) feels complete, go on to the next question.
Here are a few example questions that may be helpful for your first time:

What is my higher purpose for this year?
What blocks or fears do I have that would prevent me from attaining this?
What skills or attributes do I have to help me attain my goals?
What message of love and compassion do you have that [your name] needs to hear at this time?
After the questions feel complete, close your eyes once again, and take your Higher Self with you back to your Sanctuary. Let your Higher Self return to the magical fountain pool, knowing that it is there for you whenever you need it. Now go retrieve your mind, accepting it as a part of yourself. You may stay in your Sanctuary as long as you like, or return to it whenever you want, for it is your space, a place where you are truly free. When you are ready, return to your body through the crown chakra. Your awareness returns to the room you are in and you feel refreshed and balanced.
This technique I described above was my first experience channeling my Higher Self. I also use the same technique for channeling other beings of the Light. It is very important when you channel that you state your intent and who you are willing to let into your space, because you will be sharing your energy with them and you don't want to do that with anyone who does not have your highest interests at heart. This technique facilitates conscious channeling, that is, your consciousness does not leave your body while you channel, and you always have the choice when to stop. There is an element of surrender to Spirit involved, and people who have difficulty with control issues may find it more difficult to learn to channel until they have begun to deal with those fears of not being in control. If your desire for channeling is for your personal growth and healing, and you can learn to trust your Spirit to guide you, this technique can be learned very quickly and you will see results manifest in new ways you probably never imagined.

Thank you very much for the tips.

this is extremely interesting as i have friends who knows how to channel spirits, but this 1 you've stated seems very advanced as you have to remember a lot, i have a question though, do we have to do both grounding and clearing at the same time as that would really difficult to visualize all cords enterting from different parts of the body, e.g. visualizing the cords circulating around your body from 1 feet to the other, at the same time visualize another cord comming up your spine to all the different chakras

WOW, that is truly amazing. I am definetly going to try that once I am better at just general mediatating. Thank you so much for that.
