Sthalibhagam and sesha homam are prescribed rituals of a wedding. First laaja homam is performed before which is saptapati in a wedding; similarly, sthalibhagam and sesha homam are similar rituals; they are done because scriptures have stated so. This sthalibhagam is the beginning for all other sthalibhagam-s to be conducted later during one`s life as a grihastha. A grihastha has to perform aupasanam every day and sthalibhagam has to be performed once every fifteen days; the sthalibhagam conducted during a wedding is a precursor for the subsequent sthalibhagam, and it is considered special.
During the five days wedding rituals, aupasanam is conducted without a break for four continuous days, and a homam that is performed finally is called sesha homam to conclude the wedding rituals.
