Materialism, attachment to things of the world, includes pride. Many religious people suffer from pride: taking pleasure or even delight in being good, or religious.
Self-mortification, far from producing liberation from material things, is far more likely to cause either an unhinged mind, delusions or a masochistic taste for more suffering, experienced, of course, as joy.
If the path has been laid down, why the successive appearance of different teachers? Why would anyone reinvent the wheel, if everything were as cosy and sequential as primitive longing so easily convinces us?
