The great obstacles are these; firstly, the misunderstanding of
Self; and secondly, the resistance of the rational mind against its own
conclusions. Men must cast off these two restrictions; they must begin to
realise that Self is hidden behind, and independent of, the mental and
material instrument in which they apprehend their Point-of-View; and they
must seek an instrument other than that which insists (with every single
observation) on impressing on them what is merely its own most hateful flaw
and error, the idea of duality.
