451. The Realms
Translated from Taishō Tripiṭaka volume 2, number 99
Thus have I heard. At one time, the Buddha was dwelling in Śrāvastī, in the Jeta Grove, in Anāthapiṇḍada’s Park.
At that time, the Bhagavān said to the bhikṣus, “I will now speak of the various realms. Listen carefully and consider well, because I will tell you about them. What are the various realms? Namely,  the eye realm,  form realm, and  eye-consciousness realm; the  ear realm,  sound realm, and  ear-consciousness realm; the  nose realm,  scent realm, and  nose-consciousness realm; the  tongue realm,  flavor realm, and  tongue-consciousness realm; the  body realm,  contact realm, and  body-consciousness realm; the  thought realm,  dharma realm, and  thought-consciousness realm. These are called the various realms.”
After the Buddha had spoken this sūtra, the bhikṣus heard what the Buddha had said, and joyfully practiced in accordance.
