Letters of Sri Aurobindo
Volume II - Part 3
As regards Krishna and devotion, I think I have already answered more than once. I have no objection at all to the worship of Krishna or the Vaishnava form of devotion, nor is there any incompatibility between Vaishnava bhakti and my supramental Yoga. There is in fact no special and exclusive form of supramental Yoga: all ways can lead to the Supermind, just as all ways can lead to the Divine.
Certainly, I will help you and am helping and will always help you; the idea that I can stop doing it or will send you away has no sense in it. If you persevere, you cannot fail to get the permanent bhakti you want and the realisation you want, but 
you should learn to put an entire reliance on Krishna to give it when he finds all ready and the time come. If he wants you to clear out imperfections and impurities first, that is after all understandable. I don’t see why you should not succeed in doing it, now that your attention is being so constantly turned on it. To see them clearly and acknowledge them is the first step, to have the firm will to reject them is the next, to separate yourself from them entirely so that if they enter at all it will be as foreign elements, no longer parts of your normal nature but suggestions from outside, brings their last state; even, once seen and rejected, they may automatically fall away and disappear; but for most the process takes time. These things are not peculiar to you; they are parts of universal human nature; but they can, do and will disappear.
