Navel region
Cautioned against — not the locus of prayer
The navel (omphalos) — included here not as a locus of prayer but as a recorded warning. Barlaam of Calabria caricatured the bodily method of prayer as 'navel-gazing' (omphaloskopia), and later writers in the tradition (Theophan the Recluse, Russian starets letters) warn beginners not to misplace their attention to the navel or solar-plexus regions, which can produce psychic disturbances rather than the gathered prayer of the heart. This point is included in the system to make explicit a part of the practical pedagogy that is otherwise easy to miss.

Triad I.2 answers Barlaam’s polemical charge of “navel-gazing” by defending the bodily discipline of hesychast prayer while distinguishing it from caricature. The citation documents the controversy behind this warning marker; it does not make the navel a locus of prayer.
