योगान्तरायाः, औपसर्गिकसिद्धयः, परवैराग्येन शैवप्रसादः
संत्याज्यं सर्वथा सर्वम् औपसर्गिकमात्मनः पैशाचे पार्थिवं चाप्यं राक्षसानां पुरे द्विजाः
saṃtyājyaṃ sarvathā sarvam aupasargikamātmanaḥ paiśāce pārthivaṃ cāpyaṃ rākṣasānāṃ pure dvijāḥ
Kaya, O mga dalawang-ulit na isinilang, dapat talikdan nang lubos ang bawat dumudungis na impluwensiyang dumarating sa sarili—maging mula sa upasarga na nakahahawa at humahadlang, mula sa karumihang tulad ng piśāca, o mula sa mabigat na bahid-lupa na matatagpuan sa mga tirahan ng rākṣasa—upang ang pashu (nakagapos na kaluluwa) ay manatiling karapat-dapat sa pagsamba kay Śiva at sa landas ng disiplina ng Pāśupata.
Suta Goswami (narrating puranic injunctions to the sages of Naimisharanya)
It states that the worshipper must renounce all sources of impurity and obstructive influences, because fitness (adhikāra) and śauca protect the sanctity of Liṅga-pūjā and keep the pashu receptive to Śiva’s grace (anugraha).
By implication, Śiva as Pati is the supremely pure reality; approaching Him requires the pashu to withdraw from pasha-like defilements (grossness, fear, contamination, and tamasic influences) that cloud right knowledge and devotion.
It highlights śauca (purificatory discipline) and avoidance of tamasic/inauspicious environments—foundational observances supporting Pāśupata-oriented worship, japa, and steady pūjā without upasarga (obstruction).
