Certain qualities must be met (the heifer must be pure) and rituals performed and then the red heifer is killed and burned into ash(blood and all). The ashes will then be used to purify anyone that has touched a dead body. The whole idea behind this is to be 'cleansed' in order to perform sacrifices in the jewish temple. Couple problems right off the bat, God says there will be no more sacrifices, that Jesus' death was the last sacrifice. Also there is no current Jewish temple and when there is a new temple God says that the antichrist will seat himself there to be worshipped instead of God. So it will be literal end times, my dudes.
