The heart of a calm person is disturbed by nothing. They never lose their peace, no matter what causes problems.
This peace comes from faith. When someone loses their inner peace, everything seems confusing to them, and the simple appears difficult.
These difficulties do not come from the outside, but from within. If the heart is calm, the nerves will be calm too. In this case, one would not lose composure but instead solve the problem calmly.
If a problem cannot be solved with the mind, the nerves kick in to solve it. The agitated nerves can then signal that there is no solution, and the more the nerves are strained, the more agitated they become.
A person with a calm heart and calm nerves can achieve tranquility in thinking and acting. Their thoughts are balanced, free from disturbing influences. Therefore, they will react calmly and sensibly, far from anger or worry.
What helps a person to achieve inner peace is external tranquility, a calm environment that has no exciting influences.
For this reason, monks live in the quiet of the desert, far from the noise and shouting of people and any exciting news and events. They are calmer in their thinking, they have a calm heart and calm nerves, and are accustomed to tranquility.
Living in solitude and seclusion generally brings peace, because all senses are calm. As our saints say, the senses are the gateway to thoughts. What you see, hear, and touch gives you thoughts. When your senses rest from news, your soul also rests from thinking.
A quiet place helps the senses to rest and consequently leads to calming the thoughts, the heart, and the nerves. That's why many people avoid noisy places when they seek peace.
Those who love peace seek it with all their strength; unfortunately, others love noise and cannot live without it. They are only bored by tranquility!
