''In the inner life, why are there periods when one can no longer make a conscious effort, and if one enforces it, parts of the nature revolt or else everything in the being seems to become petrified; effort becomes the mechanical repetition of past movements. What should be done at such times?''
What is not mentioned here is the nature of the effort, for it is a certain kind of effort which leads to the result described here, which is either a revolt or a sort of—yes, petrifaction, truly, something that becomes absolutely insensible and no longer responds at all to this effort. This happens when the effort is almost exclusively mental and quite arbitrary, in the sense that it does not at all take into account the state of the rest of the being; it has its own idea, its own will, and without any consideration for the rest of the being, it imposes this will on the being as a whole. This is what usually brings about the revolt or the petrifaction. And the only thing to do is to make the mind quiet. And this is the time to make a movement of self-giving, full of peace, quietude, confidence. If one makes this movement of self-giving, of complete surrender to the divine Will, all the tension arising from the effort, an effort which could be called premature or unconsidered—all the tension arising from this effort gives way. There is a relaxation in the being. And the progress one could not make by this purely mental effort usually comes about almost automatically, by the very fact that one has relaxed in confidence and self-giving to the divine Will. <ref>http://incarnateword.in/cwm/08/28-november-1956#p22</ref>
