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, [1] the eye realm, [2] form realm, and [3] eye-consciousness realm; the [4] ear realm, [5] sound realm, and [6] ear-consciousness realm; the [7] nose realm, [8] scent realm, and [9] nose-consciousness realm; the [10] tongue realm, [11] flavor realm, and [12] tongue-consciousness realm; the [13] body realm, [14] contact realm, and [15] body-consciousness realm; the [16] thought realm, [17] dharma realm, and [18] 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.
