The interesting aspect of this thread is that it does show up the variety of views and opinions about the mourning process.
Some feel comfort from the symbolism and ritual of ashes and burial, some feel nothing, some feel nothing, but are coerced into action either by family pressure, or by social etiquette and a desire to be seen to do the 'right thing'.
But the result, as advised, is that ideally, we all cope with the loss of a loved one in a way that gives us comfort and allows us to assimilate the loss into our lives.
