In many North Indian homes a puja begins with Ganesh Pujan, kalash sthapana and the worship of the Navagraha, followed by the main deity. The kalash is commonly topped with mango leaves and a coconut wrapped in red cloth, and a sankalp is taken with the family's gotra. A havan with ahutis of ghee and samagri often closes the ritual, followed by aarti and prasad.
Katha plays a large role. The Satyanarayan Katha, for example, is usually read in Hindi or recited from the Skanda Purana with a Hindi retelling, and the family listens together before the aarti. Sundarkand Path, Hanuman Chalisa and Durga Saptashati Path are also common, especially on Tuesdays, Saturdays and during Navratri.
Customs still vary from region to region and family to family. A Punjabi family, a Bhojpuri speaking family from eastern Uttar Pradesh or Bihar, and a Marwari family may each have their own way of doing the same puja, so it helps to share any specific practices with the Pandit in advance.
