What does divination mean?
The art of “divination” is “to divine” information that is hidden. Water witching (rhabdomancy) is divination. Peering into the future would be another divination art. Reading tea leaves, or casting pig or chicken entrails onto the ground to foretell future events are other examples. Casting finger bones with runes carved into them is yet another divination art, as is consulting astrological charts. These things do not stand up well to scientific scrutiny.
