It is important to understand that our thoughts and feelings offer us great possibilities for improving ourselves
"The substance of our physical body is compact, resistant and stubborn, which is why it is hard to do anything to change it. But there are other realms in the human being, the realms of feeling and thought, whose subtle matter lends itself more easily to refinement. It only requires a bit of effort from us for our thoughts and feelings to become purer, more beautiful and richer. So this is where you must start, and the physical body will follow; it will follow much more slowly, of course, but it will follow.
It is important to understand that our thoughts and feelings offer us great possibilities for improving ourselves. Even if this work doesn’t yield immediate or spectacular results in our physical body, that too will gradually change, because without fail the inner work we do on our thoughts and feelings eventually have an effect."
