The causes of suffering are innumerable and its quality also varies a great deal, although the origin of suffering is one and the same and comes from the initial action of an anti-divine will. To make this easier to understand, one can divide suffering into two distinct categories, although in practice they are very often mixed.
The first is purely egoistic and comes from a feeling that one’s rights have been violated, that one has been deprived of one’s needs, offended, despoiled, betrayed, injured, etc. This whole category of suffering is clearly the result of hostile action and it not only opens the door in the consciousness to the influence of the adversary but is also one of his most powerful ways of acting in the world, the most powerful of all if in addition there comes its natural and spontaneous consequence: hatred and the desire for revenge in the strong, despair and the wish to die in the weak.
The other category of suffering, whose initial cause is the pain of separation created by the adversary, is totally opposite in nature: it is the suffering that comes from divine compassion, the suffering of love that feels compassion for the world’s misery, whatever its origin, cause or effect. But this suffering, which is of a purely psychic character, contains no egoism, no self-pity; it is full of peace and strength and power of action, of faith in the future and the will for victory; it does not pity but consoles, it does not identify itself with the ignorant movement in others but cures and illumines it.
It is obvious that in the purity of its essence, only that which is perfectly divine can feel that suffering; but partially, momentarily, like flashes of lightning behind the dark clouds of egoism, it appears in all who have a vast and generous heart. However, most often, in the individual consciousness it is mixed with that mean and petty self-pity which is the cause of depression and weakness. Nevertheless, when one is vigilant enough to refuse this mixture or at least to reduce it to a minimum, one soon realises that this divine compassion is based on a sublime and eternal joy which alone has the strength and the power to deliver the world from its ignorance and misery.
And this suffering too will disappear from the universe only with the total disappearance of the adversary and all the effects of his action.
