In Hinduism
Shaktism (Shakta philosophy)
Source: Google Books: Manthanabhairavatantram1) Sudāruṇa (सुदारुण) refers to “very terrible”, according to the Ṣaṭsāhasrasaṃhitā, an expansion of the Kubjikāmatatantra: the earliest popular and most authoritative Tantra of the Kubjikā cult.—Accordingly, “(Pūrṇagiri) is on the northern peak of Kailāśa and is full of countless flames. Brilliant like ten million suns, it is as if devouring the Three Worlds. It is brown and burning. Licking things up and destroying them, it is very terrible [i.e., sudāruṇa]. O goddess, it is difficult for me to see it—what to say for others! It stands in the middle of the triangular city and is adorned with walls of lightning flashes. That divine city of the supreme Lord is made of pillars of adamantine. [...]”.
2) Sudāruṇā (सुदारुणा) refers to one of the thirty-two Bhairavīs (also Dūtis) embodying the syllables of the goddess’s Vidyā, according to the Manthānabhairavatantra, a vast sprawling work that belongs to a corpus of Tantric texts concerned with the worship of the goddess Kubjikā.—The thirty-two Bhairavīs [i.e., Sudāruṇā] are the consorts of the Bhairavas presiding over the sonic energies of the thirty-two syllables of her Vidyā.

Shakta (शाक्त, śākta) or Shaktism (śāktism) represents a tradition of Hinduism where the Goddess (Devi) is revered and worshipped. Shakta literature includes a range of scriptures, including various Agamas and Tantras, although its roots may be traced back to the Vedas.
Purana and Itihasa (epic history)
Source: archive.org: Shiva Purana - English TranslationSudāruṇa (सुदारुण) (Cf. Dāruṇa) refers to “severe (penance)”, according to the Śivapurāṇa 2.3.15 (“The penance and reign of Tārakāsura”).—Accordingly, as Brahmā narrated: “[...] Then the demon Tāraka, of great strength and exploit, endowed with a lofty mind, requested permission of his mother for performing penance. The permission having been secured, that demon possessing great power of illusion and capable of deluding even experts in the magical art, thought of performing penance in order to conquer all the gods. Strictly adhering to the directions of his elders and preceptors he went to the forest of Madhu and performed a severe [i.e., sudāruṇa] penance duly, having Brahmā as his objective. [...]”.

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.

[Sanskrit to German]
Sanskrit, also spelled संस्कृतम् (saṃskṛtam), is an ancient language of India commonly seen as the grandmother of the Indo-European language family (even English!). Closely allied with Prakrit and Pali, Sanskrit is more exhaustive in both grammar and terms and has the most extensive collection of literature in the world, greatly surpassing its sister-languages Greek and Latin.
