Asceticism and Character
Savva practiced hesychasm with exceptional rigor. He kept nightly prayer vigils from one hour after sunset until the seventh hour at dawn, and ate only minimal plain food, abstaining from meat, fish, and cheese, and using no oil on his food.
He embraced a strict poverty, reportedly never owning a new coat or a second pair of shoes and giving away what he had to the poor and the sick.
His disciples testified that during their ten years with him they never saw him lose his temper, judge others, or hold a grudge. He is remembered for repeatedly teaching that humility is the foundation stone of the spiritual life, calling it the solid and indestructible cornerstone upon which the spiritual life is built.
