Sound can be used in a meditation and different sounds will impact different chakra points.

This meditation will require using some type music or sound device, such as a chime, or a bell, or taped music, or musical instrument. 

You may select not only the type of music or sound you want to use, but also the note or type of music you want or feel inclined to use in the meditation. 

If you are focusing on a certain gift associated with a certain chakra, you may want to focus your attention on that note or type of music that seems to be associated with that specific chakra. For example, if you are interested in improving your creativity, you may want to use a chime that is associated with the "D" note. Or if you want to focus on improving your communication, you may want a chime that is associated with "G".

6	A
5	G
4	F
3	E
2	D
1	C

You can experiment using different types of music or sounds as you find which notes or music works best with the meditation experience you desire.

After you have selected the type of note or music to use in your meditation, begin the basic meditation in the normal fashion..

As you place your attention on the first chakra, use the chime, bell, or music and become engaged with that sound and how it can connect to the chakra.  Notice how the music or sound impacts your perception of the chakra, it’s size, shape, clarity, alignment, as well as energy.  Be aware of the energy or image with the 1st chakra.

When ready, focus on the 2nd chakra and initiate the chime, bell, or music and again be connected with that chakra.  Notice how the music or sound impacts that chakra.  Notice the size, shape, clarity, and alignment of the chakra to the previous (the first) chakra.  Notice the energy and feeling associated with the 2nd chakra. 

When ready, focus on the next chakra and repeat the same process until you have engaged all seven chakras. After all chakras have become engaged, spend time listening to the sound or music or chime and how it affects all the chakras together.

When ready, you can end the music or sound and allow the silence to become part of you.  And slowly come out of your meditation. 

There are different variations you can create or try to this meditation.  There are many ways to meditate.  No one way is best. Select a way which works for you.

Concentrating on Sound

Eventually with practice, you will be able to use the sound in a meditation and concentrate on it so that it can be used to travel to the astral plane. You use the sound and concentrate on the sound during the meditation to the point where you are able to reduce the physical desires and feelings and concentrate only on the sound, such as a bell or a single chime. This will require intense mental concentration which seems to be a contradiction, but it works. The more you concentrate on the sound, the less the mind thinks about others and so you induce a state of self hypnosis as you may think of it.

The other aspect of sound concentration is that focusing the mind on an outside sound, the mind is not focused on the physical body. Obviously when you begin, such a meditative trance, your body needs to feel comfortable and free of pain and distraction. Again, this is hard to do if the mind is allowed to wander freely analyzing all aspects of the physical plane. So the lotus position of sitting is generally used, not because of comfort, but of discomfort. This again seems to be a contradiction and so its. By giving the mind a single focus, it can enter a trance similar to how it enters a trance with sound.

Question: Does this man the lotus position is required?
Answer: No. A sitting position that allows a single point of physical contact for the mind to focus and then gradually ignore is only required.

Question: Why the contradictions, they seem silly?
Answer: By introducing opposites into the experience, the mind is given activity which will occupy it as you consciously focus on that activity, the mind generally becomes fixated or occupied and then lulled into activity in general; similar to how a drug induced trance may be comparable.

Question: This does not make sense.
Answer: Correct. It doesn’t, but it works. Remember that you are trying to occupy the mind and free the soul. Once the mind is distracted or occupied, then the soul feels freer or willing to explore.

Question: But then how do you recall?
Answer: Because the mind is occupied, it cannot be counted on to recall, therefore, recollection of travel must occur subconsciously. This subconscious discovery is usually accomplished through a discovery meditation.

Question: This seems to be a two-step process.
Answer: Yes, you travel to the astral plane in one meditation without recollection and recall in a second.
