@Uyap: There is a huge difference between an inert thing (made of just suddhashtaka) and a living being.
When a living being stops existing in this world (filled with suffering), that is called Nibbana.
Any inert thing made out of just suddhashtaka is destroyed it is NOT called Nibbana. It is just destroyed (it cannot feel any suffering; there is no mind associated with inert thngs).
All inert things (made of suddhashtaka) are created by the minds of living beings.
