Araṇi wood is a kind of fuel used to ignite fire by friction. At the time of performing sacrifices, one can ignite a fire from araṇi wood. Although born of his dead father, King Pṛthu would still remain just like fire. Just as fire is not easily approached, King Pṛthu would be unapproachable by his enemies, even though they would appear to be very near him.
