FAQs
It highlights the moksha-oriented fruit of Vishnu-bhakti: the devotee attains Vishnu’s own abode and experiences divine joy for a vast cosmic span (a kalpa), indicating liberation-oriented proximity to Bhagavan.
By presenting “entry into Vishnu’s abode” as the result, the verse frames bhakti as a direct, grace-filled path where the devotee’s destiny culminates in Vaikuntha-like residence and bliss, not merely worldly merit.
No specific Vedanga (such as Vyakarana, Jyotisha, or Kalpa) is taught in this line; the practical takeaway is dharmic conduct and devotion that generate punya benefiting one’s lineage and leading to Vishnu-loka.
