It is true that environment contributes to the molding of character but not true that it creates or even dominates character. Thought and will are linked with our own reincarnational past. Character can be improved by effort and Grace. If we will only attend to the first and persistently carry out the inner work required on ourselves, destiny will attend to the second and not seldom remove the outer obstacles or improve the outer environment in the process.
