After the main Shradh rites (Pind Daan, Tarpan) are completed at the Ghat, and you have offered Dakshina to the Pandit:
Brahman Bhojan: If part of your Sankalpa, ensure the feeding of Brahmins is completed satisfactorily.
Pancha Bali: Ensure offerings to the cow, dog, crow, ants, and Devas have been made.
Holy Dip: Taking another dip in the Ganga after the rituals is customary for purification.
Temple Visit: Visiting the Kashi Vishwanath Temple and other important temples [9](like Annapurna Mandir, Kalabhairav Mandir) to seek blessings is highly recommended. Dedicate the merit (Punya) of your pilgrimage and rituals to your ancestors.
Charity (Daan): Giving charity (food, clothes, money) to the needy is considered very meritorious after Shradh.
Maintain Respect: Continue to maintain a respectful and pious attitude for the remainder of the day.
