  You restore temporary life to a body that has been Dead for less than 48 hours. The spell lasts for 24 hours, after which the target dies again. The target gains 1 permanent negative level while under the effect of this spell; this negative level goes away when the target dies or is permanently raised from the Dead (such as with raise Dead). The target still counts as a Dead corpse (but not undead) for the purpose of spells that revive Dead creatures, so a cleric can cast raise Dead or a similar spell on the target even while this spell is active. Once a creature has been revived with temporary resurrection, this spell cannot be used on it again until it is permanently raised from the Dead.
