प्रलय-तत्त्वलयः, नीललोहित-रुद्रः, अष्टमूर्तिस्तवः, एवं ब्रह्मणो वैराग्यम्
मृणालतन्तुभागैकशतभागे व्यवस्थितम् यमी यमविशुद्धात्मा नियम्यैवं हृदीश्वरम्
mṛṇālatantubhāgaikaśatabhāge vyavasthitam yamī yamaviśuddhātmā niyamyaivaṃ hṛdīśvaram
Having restrained himself, the disciplined yogin—purified within by yama—should thus regulate and contemplate Hṛdīśvara, the Lord abiding in the heart, as stationed in a space as subtle as one hundredth of a single fiber of a lotus-stalk.
Suta Goswami (narrating yogic teaching as transmitted in the Linga Purana)
It frames Linga-worship not only as an outer rite but as antar-yāga: the yogin installs and worships Shiva as Hṛdīśvara in the heart, in an extremely subtle locus, making inner purity and concentration central to Linga-upāsanā.
Shiva is presented as Pati—the indwelling Lord (Antaryāmin) who abides within the heart beyond gross perception. The ‘hundredth part of a lotus-fiber’ signals Shiva-tattva as subtle, luminous, and accessible through disciplined dhyāna rather than sensory grasping.
A Pāśupata-aligned dhyāna practice: purification through yama, followed by niyama-like regulation (restraint of mind/senses/breath) and focused contemplation on Hṛdīśvara in the heart as the inner Linga.
