The ego seems to have been indispensable at one time for the formation of the individual consciousness, but with the ego were born all the obstacles, sufferings, difficulties, all that now appears to us as adverse and anti-divine forces. But these forces themselves were a necessity for attaining an inner purification and the liberation from ego. The ego is at once the result of their action and the cause of their prolongation. When the ego disappears, the adverse forces will also disappear, having no longer any reason for their existence in the world.
With the inner liberation, with a total sincerity and perfect purity, all suffering will disappear, because it will no longer be necessary for the progress of the consciousness towards its final goal.
Wisdom, then, consists in working energetically at the inner transformation so that you may emerge victorious from a struggle which will have borne its fruits but will no longer have any need to exist.
