chanting
ive personally never heard of chanting as a chi kung technique
for buddhists chanting sutras is a means for other beings to recieve the buddhas teaching, when they cant partake in the teachings by themselves or from a master(like ghosts)
or it is used as a means to bless other beings..buddhists never chant to bless themselves
though chanting can be a way for an individual to recieve blessings from a bodhisattva
but as far as i know..no its not used for opening energy meridians or blockages etc..
but who knows keep going at it and if you cant find any satisfactory answers seek help from a master
Everything comes from That which cannot be named nor described because it is beyond man's comprehension; but for convenience it is called Tao.
