In Buddhism, all the suffering in the world comes from ignorance of the truth and greed for things.
In this noisy world, we are used to running all the time, deceiving ourselves to run to the end to get happiness, but we haven't even found the starting point, we haven't noticed the really important things, so we forget our feelings in this nothingness. The original meaning of nirvana is "extinguishment", not death. What extinguishes is not human nature, but the flame of greed, hatred and illusion. Maybe when we can live in the present day, we can become real people.
'It's like a strong wind blowing fire, not into the fire, but out of it.'
