This small little passage of Sri Ramana Maharshi clears all
doubts about the real significance of Sri Chakra worship.
Worship of Sri Chakra has a deep significance. There are 43
corners with sacred syllables in them. Its worship is a method for
concentration of mind.
The mind wants to move externally. It must be checked and
turned within. Its habit is to dwell on names and forms, for all external
objects possess names and forms. Such names and forms are made symbolic of
mental conceptions in order to divert the mind from external objects and make
it dwell within itself.
The murtis/vigraham, mantras, yantras, etc., are all meant
to give food to the mind in its introvert state, so that it may later become
capable of being concentrated, after which the superb state is reached
automatically.
