Letters of Sri Aurobindo
Volume II - Part 2
You need not have qualms about the time you give to action and 
creative work. Those who have an expansive creative vital or a vital made for action are usually at their best when the vital is not held back from its movement and they can develop faster by it than by introspective meditation. All that is needed is that the action should be dedicated, so that they may grow by it more and more prepared to feel and follow the Divine Force when it moves them. It is a mistake to think that to live in introspective meditation all the time is invariably the best or the only way of Yoga.
