Doing evil, one harms oneself; avoiding evil, one purifies oneself; purity and impurity depend on ourselves; no one can purify another. <ref>http://incarnateword.in/cwm/03/the-ego#p9</ref>
= Purity in Relation to other Qualities =
''' Perfection and Purity '''
It is only by a very persistent effort that one can succeed in overcoming his difficulties; and yet it seems impossible to cut oneself off completely from one's solidarity with the rest of the world. Therefore a perfect purity, a perfect perfection seem impossible so long as the world has not reached at least a certain degree of perfection. Even the ascetic, the solitary, who goes and sits in a cave or under a tree or in the jungle, cannot completely free himself from solidarity with the rest of the world. The air he breathes is full of all the vibrations of the world, the food he eats, whatever it may be, even if it is reduced to the minimum, contains the vibrations of the world; and so, it is enough for him to exist to be in solidarity with the difficulties of the world. <ref> http://incarnateword.in/cwm/06/29-december-1954#p5 </ref>
''' Aspiration and Purity '''
It is the most important for you. Particularly what you must aspire for is peace in all the being, complete equanimity, samata. The feeling that peace is not enough must go. Peace and purity and equanimity once established, all the rest must be the Mother's free gift, not a result of the demand from the being. <ref>http://incarnateword.in/cwsa/29/purity#p5</ref>
''' Sincerity and Purification '''
Sincerity! Sincerity! How sweet is the purity of thy presence! <ref> http://incarnateword.in/cwm/14/sincerity#p23 </ref>
There is, besides, a marvellous joy in being sincere. Every act of sincerity carries in itself its own reward: the feeling of purification, of soaring upwards, of liberation one gets when one has rejected even one tiny particle of falsehood. <ref>http://incarnateword.in/cwm/08/19-december-1956#p31</ref>
''' Concentration and Purity '''
Along with purity and as a help to bring it about, concentration. Purity and concentration are indeed two aspects, feminine and masculine, passive and active, of the same status of being; purity is the condition in which concentration becomes entire, rightly effective, omnipotent; by concentration purity does its works and without it would only lead to a state of peaceful quiescence and eternal repose. Their opposites are also closely connected; for we have seen that impurity is a confusion of dharmas, a lax, mixed and mutually entangled action of the different parts of the being; and this confusion proceeds from an absence of right concentration of its knowledge on its energies in the embodied Soul. The fault of our nature is first an inert subjection to the impacts of things as they come in upon the mind pell-mell without order or control and then a haphazard imperfect concentration managed fitfully, irregularly with a more or less chance emphasis on this or on that object according as they happen to interest, not the higher soul or the judging and discerning intellect, but the restless, leaping, fickle, easily tired, easily distracted lower mind which is the chief enemy of our progress. In such a condition purity, the right working of the functions, the clear, unstained and luminous order of the being is an impossibility; the various workings, given over to the chances of the environment and external influences, must necessarily run into each other and clog, divert, distract, pervert. Equally, without purity the complete, equal, flexible concentration of the being in right thought, right will, right feeling or secure status of spiritual experience is not possible. Therefore the two must proceed together, each helping the victory of the other, until we arrive at that eternal calm from which may proceed some partial image in the human being of the eternal, omnipotent and omniscient activity. <ref>http://incarnateword.in/cwsa/23/concentration#p1</ref>
''' Instinct and Purity '''
For the purity of which Sri Aurobindo speaks here is the purity of instinct, that obeys Nature's impulses spontaneously, never calculating, never questioning, never asking whether it is good or bad, whether what one does is right or wrong, whether it is a virtue or a sin, whether the outcome will be favourable or unfavourable. All these notions come into play when the mental ego makes its appearance and begins to take a dominant position in the consciousness and to veil the spontaneity of the soul. <ref>http://incarnateword.in/cwm/10/aphorism-30#p4</ref>
''' Faith and Purity '''
At every moment all the unforeseen, the unexpected, the unknown is before us―and what happens to us depends mostly on the intensity and purity of our faith. <ref>http://incarnateword.in/cwm/14/faith#p19</ref>
''' Surrender and Purity '''
Detailed surrender means the surrender of all the details of life, even the smallest and the most insignificant in appearance. And this means to remember the Divine in all circumstances; whatever we think, feel or do, we must do it for Him as a way of coming close to Him, to be more and more what He wants us to be, capable of manifesting His will in perfect sincerity and purity, to be the instruments of His Love. <ref>http://incarnateword.in/cwm/14/surrender#p7</ref>
''' Receptivity and Purity '''
If we call "perfect receptivity" the receptivity that receives only the Divine Influence and no other, it is certain—and at the same time it is perfect purity. <ref>http://incarnateword.in/cwm/16/27-november-1968#p2</ref>
''' Truth and Purity '''
When we are in the presence of hostile forces, only the purity of an absolute truth can conquer them. <ref>http://incarnateword.in/cwm/16/20-july-1935#p7</ref>
''' Peace and Purity '''
Peace and purity of the consciousness are the very foundation of the necessary change in the nature. <ref>http://incarnateword.in/cwsa/29/peace-the-basis-of-the-sadhana#p1</ref>
Peace is necessary for all; without peace and an increasing purity, even if one opens, one cannot receive perfectly all that comes down through the opening. Light too is necessary for all—without light one cannot take full advantage of all that comes down. <ref>http://incarnateword.in/cwsa/29/peace-the-basis-of-the-sadhana#p2</ref>
