Yes, Fr Seraphim Rose was condemned for his emphasis on it but seems to have been backed up by many Theologians in the EO tradition so it is disputed.
My interest is more on the OO view though, since there are prayers that seem to suggest that thre is a struggle post-death but it is never discussed.
Someone that has some idea of this please help.
