FAQs
It teaches that the decisive support at life’s most critical threshold is smaraṇa (remembrance) of Hari—where the devotee mentally hands over fear and hostility to the Lord’s protective power.
Bhakti here is expressed as single-pointed recollection of Vishnu even under threat; the devotee does not rely on personal vengeance but entrusts the removal of danger to Hari through devoted remembrance.
It reflects a practical prayoga-like instruction: controlled mental placement (nāma-karaṇa/saṃkalpa) and focused smṛti/visualization, aligning with technical disciplines that systematize recitation and contemplative application.
