Empty the mind !
Dualism or non-dualism & all other concepts,
religions, symbols, statues & shrines, etc., are all
obstructions & delusive mind contaminations that will
be hard 2 shake off when at some karma-giving time, either
in meditation, when one is at the threshold of reaching
enlightenment, one will be like harassed by them or
when at the end of time, when death is there,
one will see all sorts of hallucinations, feel
anxiety & distress that cannot but
induce an unfavorable rebirth.
All of this derives ultimately from
attachment focused upon oneself in sync with
excessive knowledge &/or over-immersion in the world.
