In general, I don't.
And it's not seva. It's a huge sin.
When I said there's no reason to burn the Gutka Sahib, I mean simply there's no reason given in the post.
I didn't come up with this.
The venerable @N30S1NGH was a hard core opponent of burning Gurbani.
Some people in our Panth are on a agan-bhet bender (I'm not talking about posters on the board, I'm talking about the actual institutions mentioned in old threads).
It is really, really hard for me to understand a reason for burning birs of Guru Sahib or Gutkas in the vast majority of circumstances. If a page is torn, you can fix the tear. If really necessary, you can replace the single page.
After a long time, the sides of pages become worn. But so what? I've done paath from older Gutkas. Why does it become necessary to burn the Gutka?
It's not a car that you're trading in for a new model.
