यतिप्रायश्चित्तविधानम्
Ascetic Atonements and Discipline
पापं हि त्रिविधं ज्ञेयं वाङ्मनःकायसंभवम् सततं हि दिवा रात्रौ येनेदं वेष्ट्यते जगत्
pāpaṃ hi trividhaṃ jñeyaṃ vāṅmanaḥkāyasaṃbhavam satataṃ hi divā rātrau yenedaṃ veṣṭyate jagat
पापं त्रिविधं ज्ञेयं वाङ्मनःकायसमुद्भवम्। अहर्निशं निरन्तरं येनेदं जगदावृतं पाशेन पशुरिव बद्धं, यावत् पतौ श्रीशिवे शरणं नीयते॥
Suta Goswami (narrating to the sages of Naimisharanya)
It frames why purification is essential before Linga-puja: the devotee must restrain and sanctify speech, mind, and body—the three doors through which pāpa accrues—so worship becomes a means of loosening pasha and turning the pashu toward Pati (Śiva).
By implication it distinguishes Śiva as Pati—the Lord beyond the world’s envelopment—while the world (and embodied beings) are shown as wrapped in karmic impurity generated through vāk, manas, and kāya.
Tri-karaṇa-śuddhi (purification of speech, mind, and body): truthfulness and mantra-discipline in speech, dhyāna and right intention in mind, and non-harming with regulated conduct in body—core supports for Pashupata-oriented sādhana and effective Shiva-puja.
