The heart has its original qualities impacted by genetics and natural religious elements, but it's biggest impact is from environment and culture. Some of the most quality human beings are those who have the least. Those who are in third world countries have the warmest hearts and would give you their last ear of corn. They would give you a ride when they have almost an empty tank and hardly any money to fill it up. These people have quality hearts that are positively influenced by their culture and religion. Their religion and culture drive their hearts. Their daily interactions, laughs, respect, and interpersonal time spent with others. This is what is driving the beautiful people because they openly expose their hearts and they let themselves be vulnerable instead of putting up a block on their heart. The more you are exposed to clean, positive hearts, the more your own heart will grow.
It's such a wonderful life and a beautiful world.
