According to early texts such as the Pali Ariyapariyesanā-sutta ("The discourse on the noble quest," MN 26) and its Chinese parallel at MĀ 204, Gautama was moved by the suffering (dukkha) of life and death, and its endless repetition due to rebirth.[34] He thus set out on a quest to find liberation from suffering (also known as "nirvana").[35] Early texts and biographies state that Gautama first studied under two teachers of meditation, namely Alara Kalama (Sanskrit: Arada Kalama) and Uddaka Ramaputta (Sanskrit: Udraka Ramaputra), learning meditation and philosophy, particularly the meditative attainment of "the sphere of nothingness" from the former, and "the sphere of neither perception nor non-perception" from the latter.[36][37][note 5]
