In fact, the most important thing for the development of the aura is not the exercise of thought but a training in the virtues

"There are two ways you can work to develop your aura. Using thought and imagination, you can try to attract the purest, most beautiful colours and surround yourself with them. But, actually, the effort involved will be a bit artificial, and the results will not last long, unless you try at the same time to practise the virtues corresponding to the colors.

In fact, the most important thing for the development of the aura is not the exercise of thought but a training in the virtues. You don't even need to do concentration exercises to develop the colours in your aura. Solely by working on nourishing the divine virtues within you, you will attract all the magnificent colours that correspond to them, without having to think about them. And so long as you practise these virtues, the colours will appear more and more beautiful and intense. "
