Celestial entities love the light, and when they catch sight of someone who is surrounded by this light which initiatic Science calls the aura, they rush towards them.
If I ask you, ‘Do you really long for love, peace, health and beauty?’ you will all reply, ‘Oh, yes! We want nothing but this!’ So then, what are you doing to obtain them? All blessings cannot come to you simply by chance. The best way to attract them is to work on your aura: vivify it with your love, illuminate it with your wisdom, make it powerful with your strength of character, and make it clear and transparent with your purity. Even if you do no concentration exercises to develop the colors of your aura, simply working within to nourish the divine virtues will attract the beautiful colors corresponding to them. And then, celestial creatures who come to bathe in it will bring you their presents, and around you, human beings will feel nourished, calmed, strengthened and transported in a divine direction.
