MN 116 Isigili Sutta- Isigili: The Gullet of the Seers
Thus have i heard.
On one occasion the Blessed One was living at Rajagaha, at Isigili - the Gullet of the Seers. There he addressed the bhikkhus thus: "Bhikkhus do you see that mountain Vebhara?" Bhikkhus: "Yes, venerable sir." Buddha: "There used to be another name, another designation, for that mountain Vebhara. Bhikkhus, do you see that mountain Pandava?" Bhikkhus: "Yes, venerable sir."
"There used to be another name, another designation, for that mountain Pandava. Bhikkhus, do you see that mountain Vepulla?" bhikkhus: "Yes, venerable sir." Buddha: "There used to be another name, another designation, for that mountain Vepulla. Bhikkhus, do you see that mountain Gijjhakuta - the Vulture Peak?" Bhikkhus: "Yes, venerable sir." Buddha: "There used to be another name, another designation, for that mountain Gijjhakuta - the Vulture Peak. Bhikkhus, do you see that mountain Isigili - the Gullet of the Seers?" Bhikkhus: "Yes, venerable sir."
Buddha:"There used to be this same name, this same designation, for this mountain Isigili - the Gullet of the Seers. For in former times five hundred paccekabuddhas dwelt long on this mountain, the Gullet of the Seers. They were seen entering into this hill; once gone in, they were no longer seen. People who saw this said: 'This mountain swallows up these seers.' And so it was that this came to be named 'The Gullet of the Seers.' I shall tell you, bhikkhus, the names of the paccekabuddhas, I shall relate to you the names of the paccekabuddhas, I shall teach you the names of the paccekabuddhas. Listen and attend closely to what I shall say." Bhikkhus: "Yes, venerable sir," the bhikkhus replied.
The Blessed One said this: "Bhikkhus, the paccekabuddha Arittha dwelt long on this mountain Isigili. The paccekabuddha Uparittha dwelt long on this mountain Isigili. The paccekabuddha Tagarasikhin... Yasassin...Sudassana...Piyadassin...Gandhara...Pindola... Upasabha...Nltha... Tatha...Sutava...Bhavitatta dwelt long on this mountain Isigili. "
"These saintly beings, free from desires, rid of suffering, Who each achieved awakening by himself. Hear me relate the names of these, the greatest Of men, who have plucked out the dart of pain."
Arittha, Uparittha, Tagarasikhin, Yasassin, Sudassana, and Piyadassin the enlightened, Gandhara, Pindola, Upasabha as well, Nltha, Tatha, Sutava, Bhavitatta.
"Sumbha, Subha, Methula, and Atthama, Then Assumegha, Arugha, Sudatha And Hingu, and Hinga, the greatly powerful, Paccekabuddhas no more led to being.
Two sages named Jali, and Atthaka, Then Kosala the enlightened, then Subahu, Upanemi, and Nemi, and Santacitta Right and true, immaculate and wise.
Kala, Upakala, Vijita, and Jita; Anga, and Panga, and Gutijjita too; Passin conquered attachment, the root of suffering; Aparajita conquered Mara's power. Satthar, Pavattar, Sarabhanga, Lomahamsa, Uccangamaya, Asita, Anasava, Manomaya, and Bandhumant the free from pride, Tadadhimutta stainless and resplendent;
Ketumbaraga, Matanga, and Ariya, Then Accuta, Accutagama, Byamaka, Sumangala, Dabbila, Supatitthita, Asayha, Khemabhirata, and Sorata,

Then Bodhi, Mahanama the supreme, Bharadvaja with fair-crested mane; Tissa and Upatissa not bound to being; Upasidarin, and Sidarin, free from craving.
Enlightened was Mangala, free from lust; Usabha cut the net, the root of suffering. Uparuta attained the state of peace, Purified, excellent, truly named.
Jeta, Jayanta, Paduma, and Uppala, Padumuttara, Rakkhita, and Pabbata, Manatthaddha glorious, Vltaraga And Kanha enlightened with mind released.
"These and also other great and mighty Paccekabuddhas no more led to being Honour these sages who, transcending craving, Have attained final Nibbana, past all measure."
In summary, reflecting on the changes that even geographical features undergo, the Buddha then recounts the names of Paccekabuddhas (silent buddhas) of the past who have formerly lived in Mount Isigili near Rājagaha.
