Translation of "postojanost" into English

Sve što tražim je da zakoračite sa mnom u beskonačnost gde postojanost, tišina i mir, beskrajnom prazninom vladaju.

All I ask is that you step with me into the boundlessness where constancy, quietude and peace, infinite emptiness reign.

Pre nego što se ona vrati iz Bafala, moram sve da završim, zbog prokletstva moje postojanosti.

Before she gets back from Buffalo, I have to perform errands for that bane of my persistence.
