Perfecting the being

As you pursue this labour of purification and unification, you must at the same time take great care to perfect the external and instrumental part of your being. When the higher truth manifests, it must find in you a mind that is supple and rich enough to be able to give the idea that seeks to express itself a form of thought which preserves its force and clarity. This thought, again, when it seeks to clothe itself in words, must find in you a sufficient power of expression so that the words reveal the thought and do not deform it. And the formula in which you embody the truth should be manifested in all your feelings, all your acts of will, all your actions, in all the movements of your being. Finally, these movements themselves should, by constant effort, attain their highest perfection.
