Quotes by Mystics

Some of these beginners, too, make little of their faults, and at other times become over-sad when they see themselves fall into them, thinking themselves to have been saints already; and thus they become angry and impatient with themselves, which is another imperfection. Often they beseech God, with great yearnings, that He will take from them their imperfections and faults, but they do this that they may find themselves at peace, and may not be troubled by them, rather than for God's sake; not realizing that, if He should take their imperfections from them, they would probably become prouder and more presumptuous still. They dislike praising others and love to be praised themselves; sometimes they seek out such praise. Herein they are like the foolish virgins, who, when their lamps could not be lit, sought oil from others.
San Juan de la Cruz
No matter how much individuals do through their own efforts, they cannot actively purify themselves enough to be disposed in the least degree for the divine union of the perfection of love. God must take over and purge them in that fire that is dark for them, as we will explain.
San Juan de la Cruz
There is another reason also why the soul has traveled safely in this obscurity; it has suffered: for the way of suffering is safer, and also more profitable, than that of rejoicing and of action. In suffering God gives strength, but in action and in joy the soul does but show its own weakness and imperfections. And in suffering, the soul practices and acquires virtue, and becomes pure, wiser, and more cautious.
San Juan de la Cruz
Spiritual growth is the gradual, I would say, transition from a God of tradition to a God of experience.
Neville Goddard
God has made different religions to suit different aspirants, times, and countries. All doctrines are only so many paths; but a path is by no means God himself. Indeed, one can reach God if one follows any of the paths with whole-hearted devotion...One may eat a cake with icing either straight or sidewise. It will taste sweet either way.
Ramakrishna
