Kāla-vañcana (Overcoming/Outwitting Time) and the Pañcabhūta Basis of the Body
निद्रालस्यं महा विघ्नं जित्वा शत्रुं प्रयत्नतः । सुखासने स्थितो नित्यं शब्दब्रह्माभ्यसन्निति
nidrālasyaṃ mahā vighnaṃ jitvā śatruṃ prayatnataḥ | sukhāsane sthito nityaṃ śabdabrahmābhyasanniti
Having overcome, through earnest effort, the enemy of sleep and lethargy—this great obstacle—one should ever remain seated in a comfortable posture and continuously practice contemplation on Śabda-Brahman, the Divine Reality realized through sacred sound.
Lord Shiva (teaching Uma/Parvati in the Umāsaṃhitā context)
Tattva Level: pashu
Shiva Form: Dakṣiṇāmūrti
Shakti Form: Pārvatī
Role: teaching
It teaches that nidrā (sleep) and ālasya (lethargy) are major inner obstacles to sādhanā; by conquering them, the seeker becomes fit for steady practice of sacred sound, which purifies the bonds (pāśa) and turns the mind toward Pati (Shiva) and liberation.
Śabda-Brahman practice commonly takes the form of mantra-japa and reverent recitation of Shiva-nāma while seated in composure; this supports Saguna worship (such as Linga devotion) by stabilizing attention, making the offering of mind and breath to Shiva continuous.
Maintain a steady, comfortable seated posture (sukhāsana) and perform regular mantra-abhyāsa—especially Shiva-nāma or the Pañcākṣarī (Om Namaḥ Śivāya)—with alertness, deliberately avoiding drowsiness and inertia.
