  In Buddhist texts
  The term Rishi found mentions throughout the Buddhist texts. In Pali, they are known as "Isi"s. A Rishi can also be called a Buddha, Paccekabuddha, Arhat or monk of high rank. In Buddhist Pali literature, Buddha is called many times as "Mahesi"(Pali; Sanskrit: Maharṣi; meaning the greatest sage).  The Isigili Sutta in Pali Canon, mentions the name of Five hundred Rishis (Paccekabuddhas). The Buddhist text, Mahamayuri Tantra, written during 1–3rd centuries CE, mentions Rishis throughout Jambudvipa (modern day India, Pakistan, Afghanistan, Bangladesh, Nepal) and invokes them for the protection of the Buddhadharma.
  Many Jatakas also mentions various Rishis. The Naḷinikā Jātaka (Jā 526) introduces a past life of the Buddha, a Rishi(Isi), living alone in the Himālayas. His son, who was also a Rishi, was named Isisiṅga (Pali; Sanskrit:Ṛṣyaśṛṅga). The Agastya Jataka (Sanskrit; Pali: Akitta Jataka) story, mentions Bodhisattva, named Agastya(Sanskrit; Pali: Akkhata) as Rishi.
