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
おお二度生まれの者たちよ、プラーナーヤーマの修練によって内なる自己は清められ、ラジャスの塵を離れたヴィラジャとなる。同様に、食の摂り方も規定に従い整えるべし—一日一食、あるいは(許され定められる時には)蜜と肉、また未調理の食も—法に随って守り、ヨーガの安定とパティ(シヴァ)へのバクティを支える浄化の行とせよ。
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.
