As the name suggests, Sumangali Pooja is done to seek blessings from ancestral woman in family who has lived and passed away from this world as a married woman or sumangali. Different kind of traditions and custom are followed based on policies followed by family and all of these policies need to be taken to account before going ahead with Sumangali Pooja.
Usually, the number of Sumangalis invited to attend Pooja range between 3, 5 7 or 9. The count is entirely based on the number of married woman available in family. Also, there is a practice to invite Sumangalis from outside so as to balance count.
Pooja begins once the entire member of family assembles and every family member is bound to invoke blessings from these Sumangalis so as to have a prosperous life ahead. Usually every married woman strictly follows Sumangali Pooja so as to ensure long life of their partner.
