 According to Max Muller – a professor of Sanskrit and Indology at the Oxford University, the sage Angiras in Vedic literature is different from the plural term "Angirasa", and these terms refer to different people.The "Angiras" rishi is different from the group of sorcerers in "Atharvaveda" also named "Angirasa", and according to Muller, the Vedic rishi is also different from a class of divine beings who too are called "Angirasa" in the Vedic texts and described as "sprung from coals ("angara")".In Buddhist Pali canonical texts such as "Digha Nikaya", Tevijja Sutta describes a discussion between the Buddha and Vedic scholars of his time.
