To regain ritual purity after contact with technology deemed "infidel," a Yuuzhan Vong endured a torturous ordeal known as Purification.
Following extensive prayer sessions led by the priest caste, the defiled Yuuzhan Vong would be immersed in a receptacle teeming with carnivorous organisms, akin to the ngdin, that devoured the corrupted tissue. Although brief, lasting merely two minutes, this procedure demanded considerable fortitude, as it was intensely agonizing, characteristic of Yuuzhan Vong traditions.
