Seneca
– I realized that your grief should not be intruded upon while it was fresh and agonizing, in case the consolations themselves should rouse and inflame it: for an illness too nothing is more harmful than premature treatment. So I was waiting until your grief of itself should lose its force and, being softened by time to endure remedies, it would allow itself to be touched and handled.

[Now] I shall offer to the mind all its sorrows, all its mourning garments: this will not be a gentle prescription for healing, but cautery and the knife.

In consonance with his strategy for inoculating oneself against misfortune, Seneca considers the benefits of such a raw confrontation of sorrow:

Let those people go on weeping and wailing whose self-indulgent minds have been weakened by long prosperity, let them collapse at the threat of the most trivial injuries; but let those who have spent all their years suffering disasters endure the worst afflictions with a brave and resolute staunchness.
Everlasting misfortune does have one blessing, that it ends up by toughening those whom it constantly afflicts.
