Letters of Sri Aurobindo
Volume IV - Part 1
These small things of the physical mind [such as being disturbed by the defects of others] are such as everybody has and they will fall off when the truer wider consciousness comes out. You have the understanding in your mind, but these things persist because they really belong to the smaller vital part and when 
that part widens, then they will no longer be able to recur. One can discourage them by keeping certain ideas in mind, such as that the things which vex you belong to the nature and can go only with the change of the nature, that one has to do the work well oneself but not be troubled by the defects of others in their work, that a quiet inner will for their doing right is more effective than getting vexed and disturbed by their lapses. But fundamentally it is by the widened consciousness in your mind and vital and physical that you will be quite freed from these small reactions. You have only to continue with the Mother’s Force working in you and these things will smooth themselves out hereafter.
