==Mantra In Sri Aurobindo’s Yoga==
As a rule the only mantra used in this sadhana is that of the Mother or of my name and the Mother. The concentration in the heart and the concentration in the head can both be used—each has its own result. The first opens up the psychic being and brings bhakti, love and union with the Mother, her presence within the heart and the action of her Force in the nature. The other opens the mind to self-realisation, to the consciousness of what is above mind, to the ascent of the consciousness out of the body and the descent of the higher consciousness into the body. <ref>http://incarnateword.in/cwsa/29/mantra-and-japa#p27</ref>
=How Of Japa?=
Japa means a mome
nt when all physical life is EXCLUSIVELY for the Divine. A moment when nothing but the Divine exists—every single cell of the body, each second, is EXCLUSIVELY for the Divine, there is nothing but the Divine. <ref>http://incarnateword.in/agenda/03/february-3-1962#p75</ref>
==Need For Quietness Of Mind, Bhakti==
The japa is usually successful only on one of two conditions,—if it is repeated with a sense of its significance, a dwelling of something in the mind on the nature, power, beauty, attraction of the Godhead it signifies and is to bring into the consciousness, that is the mental way,—or if it comes up from the heart or rings in it with a certain sense or feeling of bhakti making it alive, that is the emotional way. Either the mind or the vital has to give it support or sustenance. But if it makes the mind dry and the vital restless, it must be missing that support and sustenance. There is of course a third way, the reliance on the power of the mantra or name in itself, but then one has to go on till that power has sufficiently impressed its vibrations on the inner being to make it at a given moment suddenly open to the Presence or the Touch. But if there is a struggling or insistence for the result, then this effect which needs a quiet receptivity in the mind is impeded. That is why I insisted so much on mental quietude and on not too much straining or effort—to give time to allow the psychic and the mind to develop the necessary condition of receptivity… <ref>http://incarnateword.in/cwsa/29/mantra-and-japa#p38</ref>
==Surrender==
Perfect surrender, that is, spontaneous surrender, which requires neither effort nor anything—a surrender that must be perfectly spontaneous… This, too, is something that is attained little by little; that's why I said that the mantra is progressive, in the sense that it grows more and more perfect.<ref>http://incarnateword.in/agenda/06/february-19-1965#p18</ref>
==Dealing With Obstacles In Japa==
The fear, anger, depression etc….. These resistances rise and then, if one takes the right attitude, slowly or quickly clear away. One has to observe them and separate oneself from them, persisting in the concentration and sadhana till the vital becomes quiet and clear.<ref>http://incarnateword.in/cwsa/30/inner-experiences-in-the-state-of-samadhi#p37</ref>Lack of repetition impairs the effect of mantras. <ref>http://incarnateword.in/cwm/03/impurity#p7</ref>
