Manrique or Louis de Aranda?

Does anyone have any idea who wrote this poem?

" O World! So few the years we live,
Would that the life which thou dost give
Were life indeed!
Alas! Thy sorrows fall so fast,
Our happiest hour is when at last
The soul is freed.

Our days are covered o'er with grief,
And sorrows, neither few nor brief
veil all in gloom;
Left desolate of real good,
Within this cheerless solitude
No pleasures bloom."

Thanks!

This is a prose Commentary by Luis de Aranda
The following stanzas of the poem were found in the author's pocket after his death on the field of battle:

"Thy pilgrimage begins in tears
And ends in bitter doubts and fears,
Or dark despair;
Midway so many toils appear,
That he who lingers longest here
Knows most of care.
"Thy goods are bought with many a groan
By the hot sweat of toil alone,
And weary hearts;
Fleet-footed is the approach of woe,
But with a lingering step and slow
Its form departs."

I hope I helped
