Pali is the language spoken by the Buddha. I’ve been doing some research into the language, and tonight a concept became clear to me.
The Pali word for Nirvana (Nibbana) is “extinction” or “quenching,” as in the extinction of a fire. It is alternatively interpreted as “blowing out.”
The Pali word for grasping (upadana), which is one of the causes of suffering in the world, is “fuel.”
So, when the fire runs out of fuel, it is extinguished. When we stop grasping, there is Nirvana.
