यतिप्रायश्चित्तविधानम्
Ascetic Atonements and Discipline
प्राणायामेन शुद्धात्मा विरजा जायते द्विजाः एकान्नं मधुमांसं वा अशृतान्नं तथैव च
prāṇāyāmena śuddhātmā virajā jāyate dvijāḥ ekānnaṃ madhumāṃsaṃ vā aśṛtānnaṃ tathaiva ca
Ó duas-vezes-nascidos, pela disciplina do prāṇāyāma o ser interior é purificado e torna-se viraja, livre do pó do rajas. Do mesmo modo, observe-se uma alimentação regulada—uma única refeição, ou (quando prescrito) mel e carne, e também alimento não cozido—conforme a regra, como regime purificatório que sustenta a firmeza do yoga e a bhakti para com Pati (Śiva).
Suta Goswami (narrating Linga Purana teachings to the sages of Naimisharanya)
It links outer worship to inner eligibility: prāṇāyāma and disciplined āhāra purify the pashu (individual soul) by reducing rajas, making the mind fit for steady Linga-dhyāna and Śiva-pūjā.
Śiva-tattva is implied as the stainless Pati; the seeker becomes “viraja” (free from rajas) by yogic purification, aligning the pashu toward the purity needed to approach the transcendent Lord beyond pasha (bondage).
Prāṇāyāma is primary, supported by āhāra-niyama (regulated diet such as single-meal observance and other prescribed foods) as an auxiliary discipline in a Shaiva/Pāśupata purification regimen.
