The Tathagata accepted a small cicada as a disciple, named it Jin Chan, and allowed it to practice in seclusion after reincarnation. The mortal world is too chaotic, and the Tathagata wants an eminent monk to go to the West to obtain scriptures and save all sentient beings. The road to the West to obtain Buddhist scriptures was full of hardships and dangers.
