How can I help the soul of a family member who died suddenly?

The primary remedy prescribed by the Garuda Purana is Narayan Bali, which should be performed as soon as possible after the death, ideally before the eleventh day (Ekadasha), though it can be performed at any time afterward. Once Narayan Bali is completed, the soul is cleansed of the taint of its unnatural death and the standard channel for Shraddha offerings is restored. Following Narayan Bali, the family should continue with annual Shraddha during Pitrupaksha, regular Tarpan, and Pinda Daan at sacred sites like Prayagraj or Gaya.
