It teaches that bodily steadiness and ease are supports for inner worship—when the body is calmly seated, the mind becomes fit for Shiva-oriented practice (japa, dhyāna, and pūjā), leading the soul (paśu) toward Shiva’s grace (pati).
Before linga-pūjā, mantra-japa, or visualization of Saguna Shiva, the devotee is instructed to adopt a stable posture; this makes attention one-pointed so the offering, remembrance, and recitation are performed without restlessness.
It suggests beginning Shiva-sādhana by taking a suitable āsana (a steady, comfortable seated posture) and then resuming the prescribed practice—typically preparation for Panchākṣarī japa (Om Namaḥ Śivāya) and dhyāna, often alongside bhasma and rudrāksha observances in Shaiva discipline.
