It's easy to say that death and dying causes suffering. It definetly looks like that on the surface. But what if that's not the case?
Maybe it's our attachment to forms (people, pets, material possessions - our own physical form etc) that causes the suffering.
Forms belong to the world of forms and therefore are in a state of flux.
Clinging to 'things', whether it's to a person or a pet, or a house, or your body, will cause you to suffer at the moment it gets taken away.
Why cling to something that will one day be 'unclingable'?
To not cling is not being cold.
If anything, it's being warm.
'True love is letting go', as the saying goes.
The formless world that exists behind all forms - now there's a wonder.
