यदुवंश-प्रवचनम्: हैहय-क्रोष्टु-वंशविस्तारः (कृतवीर्यार्जुनादि, ज्यामघ-विदर्भ-शात्वत-पर्यन्तम्)
ज्यामघस्याभवद्भार्या शैब्या शीलवती सती सा चैव तपसोग्रेण शैब्या वै सम्प्रसूयत
jyāmaghasyābhavadbhāryā śaibyā śīlavatī satī sā caiva tapasogreṇa śaibyā vai samprasūyata
A esposa de Jyāmagha era Śaibyā—virtuosa na conduta e firme na castidade. Pelo poder de sua austeridade intensa, essa Śaibyā concebeu e deu à luz descendência.
Suta Goswami (narrating to the sages of Naimisharanya)
Though not a direct linga-puja instruction, it upholds a core Shaiva principle: tapas (disciplined inner heat) purifies the pashu (individual soul) and supports dharmic outcomes, preparing one for devotion and worship of Pati (Shiva).
Implicitly, it reflects Shiva-tattva as the unseen power that fructifies merit: intense tapas aligns the devotee with dharma, loosening pasha (bondage) and enabling auspicious manifestation—an expression of Pati’s overseeing grace in the cosmic order.
Tapas—sustained austerity and self-restraint—is highlighted as a yogic discipline; in Shaiva framing it functions like Pashupata-oriented inner purification that strengthens steadiness (niyama) and moral power (dharma-bala).
