I dont. My mum 50-50 but the beliefs of 'proving' has been passed down.
Leave a soup ladle in an empty pot & put them on the stove.
Make sure your rice bin is full.
The deceased are believed to touch only these 2 items in his own home or his eldest son home. Those who has god outside the mian door, cover them to let the decease into the house, else they'll be blocked.
Best to have someone staying in the deceased house during the 49 days. The deceased will miss them if he comes back but finds it empty.
