It could be said that this is true because if someone's peace of mind is caused by money, there will be many rich people whose lives are very peaceful.
In fact, there are still many rich people who do not get all of that and in fact they do not find peace at all with the abundant amount of wealth they have.
We will gain peace if we are able to be grateful for anything and we can share it with those closest to us. But even so, wealth will be much better as long as we can enjoy and share with each other, with wealth we can help other people so that they can gain happiness.
A rich person whose life is not peaceful or cannot enjoy his prime is a rich person who has more problems or debts in his life so that he is always uneasy even though he has a lot of money by his side because he is not able to manage his work and the time he has very well. But try to look at rich people who live calm and peaceful lives while enjoying their wealth in this world, there are definitely good things they do in life but these things are still not done by other rich people in this world so there are still difficulties that occur in their lives even though they already rich.
