Yes, it's an art. We need to learn how to feel peace inside.
Don't believe me?
Match it with your life and you will understand better.
Can you remember when was the last time you felt jealous? Is that the same as your childhood jealousy or it's different? Can you handle it better now?
If you are seeing a positive change then I have to say, you learned the art. And if not, then don't worry. It's nothing you inherited and can't be learned now. You still can practice and become a master of this.
And this is not about jealousy or anything particular. But as a whole, not focusing on what distracts us from our inner peace is surely an art.
But how do we learn and master this art?
Practice and you will find peace and calm gradually.
Calm down and make yourself de-stressed about life.
Don't worry to control your life, believe that sometimes it's okay to let it flow.
Practice feeling happy for others.
Set life goals without materialistic attachment.
Make self-development your priority.
There are hundreds and thousands of things that can help you feel calm and less stressed about life. Like meditation, spiritual growth, and self-development. Try doing these. Practice making yourself more attached to your own life not with the earthly thing. Be focused on the greater things.
May peace be upon you.
