In Hinduism
Purana and Itihasa (epic history)
Source: archive.org: Shiva Purana - English TranslationSarvamantra (सर्वमन्त्र) refers to “all formulas (=mantras)”, according to the Śivapurāṇa 2.3.21 (“Nārada instructs Pārvatī”).—Accordingly, as Nārada said to Pārvatī: “O goddess, listen to the wonderful efficacy of this formula on hearing which Śiva becomes excessively pleased. This formula is a king of all formulas [i.e., sarvamantra]. It yields all cherished desires, bestows all worldly pleasures and salvation, and appeals much to Śiva. Repeating this formula in accordance with the injunctions you shall propitiate Śiva. He will certainly appear before you”.

The Purana (पुराण, purāṇas) refers to Sanskrit literature preserving ancient India’s vast cultural history, including historical legends, religious ceremonies, various arts and sciences. The eighteen mahapuranas total over 400,000 shlokas (metrical couplets) and date to at least several centuries BCE.
Shaivism (Shaiva philosophy)
Source: Brill: Śaivism and the Tantric TraditionsSarvamantra (सर्वमन्त्र) refers to “all mantras”, according to the Guhyasūtra chapter 3.—Accordingly, “[...] One should recite the navātman one lakh (lakṣa) times … for siddhi: one who [thus] observes such an excellent observance for a year or just six months attains lowest, middling or best siddhi. But if, while observing such a vrata, someone recites five lakh times, then [that mantra] succeeds [for him] (siddhyate), and all mantras (sarvamantra—sarve mantrāśca) succeed for him and he attains the fruits he desires. [...]”.

Shaiva (शैव, śaiva) or Shaivism (śaivism) represents a tradition of Hinduism worshiping Shiva as the supreme being. Closely related to Shaktism, Shaiva literature includes a range of scriptures, including Tantras, while the root of this tradition may be traced back to the ancient Vedas.
