Debbie Mitra lights a candle at a shrine in the master bedroom of her and her husband's Edison, New Jersey home.

"Those who have bigger houses might have a spare room and put the shrine in there. Otherwise people generally use a walk-in closet because it's like a small room and it's in a quiet place. Most of my friends do it like that. We just went down to Home Depot and bought some racks and shelving, and put them up in the closet."
