Ascetic Atonements and Discipline
त्रिरात्रमुपवासाश् च प्राणायामशतं तथा रात्रौ स्कन्नः शुचिः स्नात्वा द्वादशैव तु धारणा
trirātramupavāsāś ca prāṇāyāmaśataṃ tathā rātrau skannaḥ śuciḥ snātvā dvādaśaiva tu dhāraṇā
Deve-se jejuar (upavāsa) por três noites e, do mesmo modo, realizar cem prāṇāyāmas. Depois, à noite—tendo observado a contenção prescrita, permanecendo puro e após o banho—devem-se fazer doze dhāraṇās (concentrações), como disciplina para o culto de Śiva.
Suta Goswami (narrating Shiva-vrata and yogic supports to the sages at Naimisharanya)
It links external vrata (three-night fasting and purity) with internal upāsanā (prāṇāyāma and dhāraṇā), showing that Linga-pūjā is perfected when the pashu (individual soul) is disciplined and made fit to approach Pati (Shiva).
Shiva-tattva is approached not merely through offerings but through inner steadiness: breath regulation and one-pointed dhāraṇā purify pasha (bondage: restlessness, impurity) so the pashu may turn toward the ever-pure Pati.
A combined vrata-yoga regimen: trirātra-upavāsa (three-night fast), prāṇāyāma-śata (100 breath cycles), ritual purity through bathing, and dvādaśa-dhāraṇā (twelve focused concentrations) supporting Shiva-pūjā in a Pāśupata-oriented discipline.
