About Śramaṇa

Śramaṇa means "one who labours, toils, or exerts themselves " or "seeker, one who performs acts of austerity, ascetic". The term in early Vedic literature is predominantly used as an epithet for the Rishis with reference to śrama associated with the ritualistic exertion. The term in these texts doesn't express non-Vedic connotations as it does in post-Vedic Buddhist and Jain canonical texts. During its later semantic development, the term came to refer to several non-Brahmanical ascetic movements parallel to but separate from the Vedic religion. The Śramaṇa tradition includes Jainism, Buddhism, and others such as the Ājīvika, Ajñanas and Cārvākas.
