The dark fortnight of Aswayuja (September–October) is known as the Pitru Paksha (Mahalaya), which is especially sacred for offering oblations to departed ancestors. The last day of this period, the dark moon day, called "mahalaya Amavasya", is considered the most important day in the year for performing obsequies and rites. The manes return to their abode on the evening of Deepavali. Due to the grace of the Yama, it has been ordained that offerings made during this period benefit all the departed souls, whether they are connected to you or not.
