the 3 ritual bathing

A tradition among the cardinal bloodline members. The 3 bathing rituals are performed at the 3 crucial stages of life of a cardinal blood. The 3 sacred lakes hidden from the general population signify the life stages of a cardinal blood. The first bathing ritual is performed after birth. The second bathing ritual is performed a day before a cardinal blood goes into service(working for the completion of the 'Final task'). The third is reserved for those who fulfilled their duty of service and died honorably. 
Those unable to perform the 3 bathing rituals will not receive the first salvation. Therefore they must reprimend it in their next life.
