To win this victory we must build up in ourselves a mentality whose quality is the opposite of that of the surrounding medium. We must, little by little, day by day, fill our minds with the loftiest, purest, most disinterested thoughts we can conceive of, and through our deliberate care they must become sufficiently living that they awaken in us each time a temptation to think wrongly comes to us from outside and rise in their dazzling splendour to face the shadow which constantly lurks in wait ready to assail us.
Let us light within ourselves the fire of the ancient vestals, the fire symbolising divine intelligence, which it is our duty to manifest. Moreover, the building up of a synthesis of pure and powerful thoughts does not lead solely to our own happiness. The clearer and higher the flame, the more light it sheds around it.The star we allow to shine through us will foster the birth of similar stars by its example; fortunately, not only darkness and ignorance, but also knowledge and light can be contagious. In addition, the care we take to remain conscious of our highest thoughts will compel us to control our thoughts constantly, and this control is gradually obtained by the methods I outlined to you last month — analysis, reflection, meditation,etc.
Those who have achieved the control of their mental being can emanate at will a certain portion of their intellectual power, send it wherever they think proper, while remaining perfectly conscious of it.These emanations, which are true messengers, will take your place wherever, physically, it is for any reason impossible for you to go yourself. The advantages of this power will be easily apparent to you.
A thought which is skilfully directed and sustained can, by affinity, awaken to consciousness a glimmer of wisdom in many minds as yet wrapt in darkness, and thus set them on their way towards progressive evolution; it can serve as an intermediary for one who is sick by drawing towards him the vital forces needed to cure him; it can watch over a dear friend and protect him from many dangers, either by warning him through mental communication and through his intuition or by acting directly on the cause of peril.
