Kāśyapa said, “If someone from another training wishes to enter the Buddha’s teaching and cultivate the religious life, they will wait to be observed for four months to assess their many ideas. Afterward, they can leave home and receive the Saṅgha’s assent. Now, I would be willing to wait for four years of observation to enter the Buddha’s teaching to receive the Saṅgha’s assent. Afterward, I’ll leave home and accept the precepts.”
