When I first entered an Orthodox Church, right after I came to faith in Christ and was seeking a fellowship, a cloud of incense floated above the altar. A large Icon of Christ on the Cross seem to almost rise out of the cloud, the chanter was reading the Divine Liturgy in a sing song Greek and I felt as if I was transported back in time to the Byzantine empire.
The flesh craves a religion of the senses, God have mercy!
I also spent a lot of time in the hesychastic practice of prayer using a prayer rope from Mt. Athos...strange times...
