Yī kě chuán zhī rén bù chuán, shī rén. Bùkě chuán zhī rén ér chuán, shī jiàn. Rú rèn rén bù zhēn, níng shī rén wù shī jiàn. Zìgǔ jiē rán, fēi wúbèi zhī lìn yě.
If there is someone that the art can be transmitted to, but it is not, that person is lost. If someone who can not receive the transmission is taught, the sword art is lost. So recognize the people who are right. Rather lose a person than lose the sword art. Since ancient times it was always this way, it is not our generations stinginess.
