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
Debe guardarse ayuno (upavāsa) durante tres noches, y asimismo realizar cien prāṇāyāmas. Luego, por la noche—habiendo observado la contención prescrita, permaneciendo puro y tras bañarse—deben efectuarse doce dhāraṇās (concentraciones), como parte de la disciplina para el 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.
