But of what immense worth is it for the soul to be with itself, to live, as the phrase is, with itself, discharged from the service of lust, ambition, strife, enmities, desires of every kind! If one has some provision laid up, as it were, of study and learning, nothing is more enjoyable than the leisure of old age.
At illa quanti sunt, animum, tamquam emeritis stipendiis libidinis, ambitionis, contentionis, inimicitiarum cupiditatum omnium, secum esse secumque, ut dicitur, vivere! Si vero habet aliquod tamquam pabulum studi atque doctrinae, nihil est otiosa senectute iucundius.

Variants
(Falconer): But how blessed it is for the soul, after having, as it were, finished its campaigns of lust and ambition, of strife and enmity and of all the passions, to return within itself, and, as the saying is, “to live apart”! And indeed if it has any provender, so to speak, of study and learning, nothing is more enjoyable than a leisured old age.
