You can be saved in the world, but....

I am not sinning if I say that only monks can achieve supreme bliss. You can be saved in the world, but it is impossible to be completely whitened, washed from your old self, rise the equal angelic height, to the highest spiritual creativity living in the world, that is, the whole way of worldly life, formed according to its on laws, destroys, slows down the growth of the soul. Therefore, people grow to the equal angles' heights only in laboratories called monasteries. - St. Basanuphius of Optina
