Yoshiro Tamura: The Jewel in the Topknot

Chapter 14 contains the parable of the jewel in the topknot. A powerful king rewards his soldiers for their achievements. The precious jewel in the topknot of his hair is the only thing he does not give to anyone, reserving it for a soldier of especially great merit. Just as the Buddha, who is king of the truth, has preached the Dharma in various ways, the Lotus Sutra is reserved for those who will practice the bodhisattva way in the future.
