He should work to develop the purity,
brightness, beauty, power and magnitude of his aura.
Each one of these aspects depends on the virtues he cultivates.
If a man is pure his aura becomes limpid and transparent;
if he is intelligent it becomes brighter and more luminous;
if his life is very intense his aura vibrates, too, with great intensity;
if he has developed his willpower it becomes very powerful,
and if he has concentrated all his energies on spiritual things
his aura expands and grows until it becomes immense.
And the beauty of the aura, that is the beauty of its colours,
depends on the harmony which reigns
amongst all its different qualities and virtues.
-Omraam Mikhael Aivanhov
