orthodoxgladness:

A sign of a person who has found God is peace and quiet emanating from him. – Monk Simeon of Mt. Athos.

Our natural state has become one of frenzy. We are filled with anxiety and contention. We move from one action to the next. Always trying to fill the void inside. In God, there is no more movement – as there is no more void. The hole in our Soul has been perfectly filled.

Thus we can be at peace.
