Adhyaya 23: श्वेत-लोहित-पीत-कृष्ण-विश्व-कल्पेषु रुद्रस्वरूप-गायत्री-तत्त्ववर्णनम्
ये मां रुद्रं च रुद्राणीं गायत्रीं वेदमातरम् वेत्स्यन्ति तपसा युक्ता विमला ब्रह्मसंगताः
ye māṃ rudraṃ ca rudrāṇīṃ gāyatrīṃ vedamātaram vetsyanti tapasā yuktā vimalā brahmasaṃgatāḥ
タパス(苦行)によって身を律し、わたしをルドラ(Rudra)として、またルドラーニー(Rudrāṇī)として、さらにヴェーダの母ガーヤトリー(Gāyatrī)として真に知る者は、清められて無垢となり、ブラフマン(Brahman)と合一し、あらゆる束縛(pāśa)を超える至上主パティ(Pati)との交わりに至る。
Suta Goswami (narrating the Linga Purana’s teaching stream to the sages, echoing Rudra-centric doctrine)
It frames Linga-centered devotion as inner realization: knowing Rudra (Pati) together with Rudrani (Shakti) and Gayatri (Vedic power) through tapas purifies the worshipper and culminates in Brahman-communion, making external worship fruitful through inner transformation.
Shiva is presented as Rudra who is not separate from Shakti (Rudrani) and is approachable through the Vedic mother-mantra (Gayatri). Realization of this unity elevates the pashu (individual soul) beyond pasha (bondage) into brahma-saṅgati (union with the Supreme).
Tapas-yoga—disciplined austerity and focused sadhana—paired with mantra-jnana (Gayatri) and Rudra-Shakti contemplation, implying japa, purity (vimala), and steady integration (yukta) as the means to liberation.
