来世长相厮守今生永不分离
[lái shì zhăng xiāng sī shŏu jīn shēng yŏng bù fēn lí]
This expresses a yearning for eternal companionship that spans lifetimes. Literally, it means 'if not in this life then together in the next life we will always be together.' Such deep and eternal love signifies someone's strong longing for unbreakable connection and unity beyond mortal limits.
