the best chakra massage I know of is to do pranayama for chakra awareness. At best imo any external type of massage with the hands might influence the mind to work on the chakra internally so it's really the mind that's doing the work. Moving the prana (life force energy) using the breath is extremely energizing to the chakras. Then doing it by the mind alone is even more powerful. And the greatest chakra experiences come through spiritual awakening.
