Thanks @metama. Aside from the practice I mentioned in this post, I also practice loving kindness meditation. It's wishing myself and others well saying to myself and other in this world phrases like "May we be happy" and "May we know peace."

The practice that you mentioned seems interesting. I'll try it. It seems like a different version of loving kindness meditation.

When you practice self love, you are definitely giving a gift to the world. Because you become a better person to others as well.
