FAQs
This verse instructs that on the thirteenth day one should arrange Lord Viṣṇu’s bathing ceremony using five sacred substances, performed strictly according to scriptural rules by qualified experts.
Because devotional rites in the Bhagavatam are meant to be performed with proper injunctions and purity; expert guidance ensures the worship aligns with scripture and remains spiritually effective.
