arjaka [阿梨樹] (; ari-ju): A tree that grows in India and other tropical areas. It is said that when a branch of this tree falls to the ground it splits into seven pieces. When the ten demon daughters in the “Dhāranī” (twenty-sixth) chapter of the Lotus Sutra pledge to protect the sutra’s votaries, they are quoted as saying, “If there are those who fail to heed our spells and trouble and disrupt the preachers of the Law, their heads will split into seven pieces like the branches of the arjaka tree.”
