หลักธรรมอันสว่างไสวอันศักดิ์สิทธิ์เหล่านี้ บัณฑิตพราหมณ์ได้ประกาศไว้แล้ว เพราะฉะนั้นอย่าภาวนามนต์โดยเหยียดเท้าออกไป; พึงนั่งกุกกุฏาสนะแล้วภาวนาด้วยวินัย ในการบูชาพติ (พระศิวะ)
Suta Goswami
It sets a rule of reverent bodily discipline: mantra-japa for Śiva should be done without disrespectful posture (feet stretched out), reinforcing purity, focus, and devotion during Linga-pūjā.
By calling the teaching “luminous” (jyotīṁṣi), it implies Śiva as Pati—the illuminating consciousness—approached through ordered practice that steadies the pashu (individual soul) and loosens pasha (bondage) via japa.
Mantra-japa performed in a disciplined seated āsana—specifically Kukkuṭāsana—rather than casually with legs outstretched, aligning pūjā-vidhi with yogic restraint.
