“Death is a release from and an end of all pains: beyond it our sufferings cannot extend: it restores us to the peaceful rest in which we lay before we were born. If anyone pities the dead, he ought also to pity those who have not been born. Death is neither a good nor a bad thing, for that alone which is something can be a good or a bad thing: but that which is nothing, and reduces all things to nothing, does not hand us over to either fortune, because good and bad require some material to work upon. Fortune cannot take ahold of that which Nature has let go, nor can a man be unhappy if he is nothing.”
From Ad Marciam De Consolatione (Of Consolation, To Marcia), cap. XIX, line 5

Mors dolorum omnium exsolutio est et finis ultra quem mala nostra non exeunt, quae nos in illam tranquillitatem in qua antequam nasceremur iacuimus reponit. Si mortuorum aliquis miseretur, et non natorum misereatur. Mors nec bonum nec malum est; id enim potest aut bonum aut malum esse quod aliquid est; quod uero ipsum nihil est et omnia in nihilum redigit, nulli nos fortunae tradit. Mala enim bonaque circa aliquam uersantur materiam: non potest id fortuna tenere quod natura dimisit, nec potest miser esse qui nullus est.

Context: The value of material things depends upon the part they play in the life of the spirit. In themselves they are neither good nor bad. They become good or bad according to whether they help or hinder the manifestation of Divinity through matter. Take for example the place of the physical body in the life of the spirit. It is a mistake to set up an antithesis between “flesh” and “spirit.” Such contrast almost inevitably ends in an unqualified condemnation of the body. The body obstructs spiritual fulfillment only if it is pampered as having claims in its own right. Its proper function is rightly understood as ancillary to spiritual purposes. The rider needs a horse if he is to fight a battle, though the horse can become an impediment if it refuses to be completely submissive to his will. In the same way the spirit needs to be clothed in matter if it is to come into full possession of its own possibilities, although the body can at times become a hindrance if it refuses to be compliant with the requirements of the spirit. If the body yields to the claims of the spirit as it should, it is instrumental in bringing down the kingdom of heaven on earth. It becomes a vehicle for the release of divine life, and when it subserves this purpose it might aptly be called the temple of God on earth.
