34-Two concurrent points lie on Pascal line

When I found way ageneralization problem at here  Yet Another Seven Circles Theorem , I think may be it is true if P is a line? I check and found problems following.



Let cyclic hexagon ABCDEFBD meets CF at HAD meets CE at GBEmeets AF at I . Three circle (ABI),(ACG),(BCH) concurrent at a point Plie on the Pascal line \over{HGI}. Similar we have three circle (EFI),(EDG),(FDH) concurrent at a point J lie on the Pascal line \over{HGI}.
