Father Placide Deseille
gave an excellent conference
on the difference between the Jesus Prayer
and the prayer of the heart.
In 2017, the French publisher Le Cerf
published a volume
with lesser known works by
Gregory of Nyssa.
Here is a review by Jean-Claude Larchet,
that gives a good idea of the content.
He gives current numbers
showing how the Orthodox Church uses digital media,
and how to use better those tools to spread the Good News today.
