The REAL marathon of prostrations (which I sometimes refer to as “Orthodox yoga”) is the Rite of Forgiveness, on the Sunday before the Great Fast starts.

Something like this service might be helpful in Lutheran parishes, too, since there are resentments and indifference to each other in every parish of every church body. But it is possible that like much else, the rite will only work in the context of the Holy Orthodox Church.
