One of the well-know ways to return to the infinite bliss that we are is to achieve it during our lifetimes i.e. reach enlightment.

Manichaeism is gnostic sect which many believe had the knowledge how to escape this prison planet.
The Manichaeans abstained from sex, from all animal food, and eggs, believing all flesh was evil if begotten by copulation.

They included the strict abomination of all matter, especially the flesh. The Devil/Satan/Demiurge created the material world and also made sex to entrap the ethereal souls in the prison of the flesh. Similar views were taught by the Essenes.
