Evening Moon Arghya (The Conclusion): After sunset, bathe or wash your hands and feet. When the Moon rises, take water, sandalwood (Chandan), Akshat, and a little milk in a vessel (Lota). Face the sky and offer Arghya to the Moon chanting this powerful mantra:
"गगनार्णवमाणिक्य चन्द्र दाक्षायणीपते।
गृहाणार्घ्यं मया दत्तं गणेशप्रतिरूपक॥"
(Meaning: O Ruby of the sky-ocean, husband of Rohini, and reflection of Ganesha! Please accept this Arghya offered by me.)
Finally, perform the Aarti and break your fast by distributing Prasad to the family.
