Is nirodha (cessation of suffering) dependent on the existence of suffering? This answer includes the following statement:


  But some other dharmas are still empty without being dependently originated, like nirodha or tathata.


A comment after the answers gives the following definitions:


  nirodha is cessation of suffering (nirvana), and tathata is true reality.


Doesn't the cessation of suffering depend on the existence of suffering, and is therefore dependently originated?
Although nirodha is usually translated "cessation", its main meaning is "restraint", "prevention" - e.g. of crime or any undesired activity/outcome. In modern Hindi, nirodh is even used as a word for condom.

If you really think about it, this makes sense. The way cessation of dukkha is achieved is through non-attachment - i.e. non-creation of conditions that make arising of dukkha possible. In other words, non-attachment is prevention of dukkha.

Prevention of X does not depend on existence of X.
