ministering to my own sores

Seneca, to Lucilius:

I have withdrawn not only from men, but from affairs, especially from my own affairs; I am working for later generations, writing down some ideas that may be of assistance to them. There are certain wholesome counsels, which may be compared to prescriptions of useful drugs; these I am putting into writing; for I have found them helpful in ministering to my own sores, which, if not wholly cured, have at any rate ceased to spread.
