The rejection of desire is essentially the rejection of the element of craving, putting that out from the consciousness itself as a foreign element not belonging to the true self and the inner nature. But refusal to indulge the suggestions of desire is also a part of the rejection; to abstain from the action suggested, if it is not the right action, must be included in the Yogic discipline. It is only when this is done in the wrong way, by a mental ascetic principle or a hard moral rule, that it can be called suppression. The difference between suppression and an inward essential rejection is the difference between mental or moral control and a spiritual purification.
These wrong movements [doubt, depression, sadness, hostility towards the Mother] belong to the universal vital Nature, but the vital of man also shares in them, makes itself a centre and field of the play of these wrong forces: in that sense they are in you. But by constant rejection they are pushed out; you feel them no longer rising in you but coming from outside. The vital still admits them because it is not yet pure of the old habit of response. You have to persist till they are entirely foreign to your nature and no longer get admittance.
