Gavra at work – R’ dovid does not just say extreme positions to keep himself popular.
I would not advise people to start with any godol, period. it is DANGEROUS. Especailly since this a subject in which every godoil agrees.
If anyone here learns as many hours in two days as R’ dovid – or r’ steinman or r’ Ovadia do in one day, maybe you can start thinking about commenting.
