Mystic Board

what Gem said.
Meditations, especially a guided one, can help tremendously.
as can a good Reiki treatment.
deep breathing with colors
if you like stones/gems/crystals, utilizing those as well in meditation
just my thoughts.

crystal singing bowls are awesome for chakra work.
or the brass bowls.
I also like any of the Native American flute music.  For me the Native American flutes strike the right chords for chakra healing and during Reiki treatments.

I believe yes, chakras can/are seen.  As a Reiki practioner I feel or see the chakras or the vibrations dependent upon the circumstances.  I don't think I learned how to see, I think I allowed the natrual-ness of the seeing to come forward.
