Inner circumference: 15.5cm, beads 10mm ★ "Rakurai no Ki" (Lightning-Struck Wood) refers to wood that has been split by natural lightning, typically including Zao wood, hard-to-split willow wood, and wood affected by weather. These trees are struck by lightning on rainy days during their normal growth process, becoming lightning-struck wood. ★ The common belief among the people is that lightning striking a tree is the work of the heavens, and that the lightning splits the wood. Ghosts are deeply feared, and it is a talisman of the strongest power to ward off evil. Lightning-struck wood is considered the supreme sacred wood in Taoist magic and was used to create spiritual artifacts. 【Special Notes】 ★ The photos were taken by an amateur with an iPhone and are posted as is.
