Praṇava-Māhātmya and the Twofold Mantra (Sūkṣma–Sthūla) in Śaiva Sādhanā
तदर्वाग्बिंदुरूपं हि नादरूपं तदुत्तरम् । तदर्वाक्कर्मलोकस्तु तदूर्ध्वं ज्ञानलोककः
tadarvāgbiṃdurūpaṃ hi nādarūpaṃ taduttaram | tadarvākkarmalokastu tadūrdhvaṃ jñānalokakaḥ
اس کے نیچے بِندو کی صورت والا لوک ہے اور اس کے اوپر ناد کی صورت والا لوک۔ اس کے نیچے کرم لوک ہے اور اس کے اوپر گیان لوک قائم ہے۔

It outlines a Shaiva hierarchy of inner and cosmic planes: karma (action-bound living) is lower, while jñāna (liberating insight) is higher, with Bindu and Nāda indicating subtle spiritual principles leading the seeker toward Shiva-realization.
The Linga is presented in Shaiva thought as a bridge from the manifest to the subtle: devotion and ritual (karma) mature into inner contemplation of Nāda-Bindu, culminating in knowledge (jñāna) that reveals Shiva as the supreme Pati beyond bondage.
Move from outer karma to inner japa and dhyāna: repeat the Panchākṣarī (Om Namaḥ Śivāya) with steady breath-awareness, listening inwardly to nāda and concentrating the mind into bindu-like one-pointedness.
