Harder to test and track since sometimes what people do and say have nothing to do with what they think/believe. Setting that aside when you reach the hereafter if one exists you will be called on the carpet and read your track record and be asked to JUSTIFY some of what you did/said in life and those whom you clinged too held on too celebrated worshipped admired. YOU WILL BE UNABLE TO LIE.
Will you be assured prepared calm relaxed or will you be terrified horrified petrified?
