Sri Aurobindo
Letters of Sri Aurobindo
Volume IV - Part 4
All X’s troubles are due partly to past Karma in another life, partly to his nature which is unable to harmonise with his 
surroundings or to master them by strong will and clear understanding or to face them with calm poise and balance. Life is for experience and growth and until one has learned one’s lesson things go on happening that are the result of one’s imperfect balance with Nature or inner imperfections. All that happens is for the best is true only if we see with the cosmic view that takes in past and future development which is aided by ill fortune, as well as good fortune, by danger, death, suffering and calamity, as well as by happiness, success and victory. It is not true if it means that only things happen which are fortunate or obviously good for the person in the human sense.
