Gruhapravesha in many Kannada homes begins early in the morning with Ganapathi Pooje, Punyahavachana and a Vastu Homa, followed by boiling milk in the new kitchen. Some families also perform a Navagraha Homa or Satyanarayana Pooja on the same day.
Sampradaya matters a great deal. Madhwa families follow the tradition of Sri Madhvacharya, with emphasis on the worship of Vishnu, while Smarta families follow the Advaita tradition associated with Adi Shankaracharya, and Sri Vaishnava families have their own practices. Mantras, tilak and some rituals can differ accordingly.
Festivals shape the ritual year too. Gowri Ganesha habba, where Goddess Gowri is worshipped the day before Ganesha, and Varamahalakshmi Vrata are observed in many homes. Because practices vary, sharing your family's customs with the purohit helps.
