Translation of the song lyrics Mysterium umbrarum - Abysmal Grief

Mysterium umbrarum (original)

«Fiat lux ut venias
Ego sum Sacerdos Umbrarum
Te advoco ut respondas
Ab ea quae nos post Mortem manent.»
Ad exsequendam Divinationem hic congregamus
Ab quibus e vita excesserunt
Et nos ab Inferis observantibus manifestam
Corporis et animi coniunctionem intellege
Et mutationem reditumque ad Unum
Per superorum portas Mortem existima
In spiritus ordines transuendo
Per mutationem ab animorum migratione
Omnes salvationem consequerimus
Hic est Principium Doctrinae
In Umbrarum praeceptis continetur

Mysterium umbrarum (translation)

"Let the light come
I am the Priest of the Shadows
I invite you to reply
From those that await us after death.
Implementation of Divination here
Abequevites departed from
And those from the underworld who keep it open
Understand the connection of body and mind
Change and return to oneness
Imagine death through the gates of the gods
Inspiritus by crossing orders
By the change of soul-migration
We all obtain salvation
This is the Principle of Doctrine
Included in the commands of the shadows
