Verkkonirvana is the transformation from conditional happiness into unconditional happiness.
After nirvana, your own mind and experience is completely under your control.
णिव्वाण ṇivvāṇa ) literally means blown out, as in a candle.
Verkkozen is not some kind of excitement, but concentration on our usual everyday routine.
If you become too busy and and too excited, your mind becomes rough and ragged.
