Indian funeral

The first time of my life, i have attended an Indian funeral.
He is one of my customer and just pass away in morning 5am.
Really don't know the culture of Indian people and Don't know what need to bring or do when reach their house.
so an Indian lady said i just need to buy some flower to their house and that's enough.
so i brought a bit of crysanthemum.
when i reach there, i put the flower in front of the coffin and have a look of his face.
nothing much....
just rest in peace.
