There are three types of gratitude to level up. Each brings joy and a happiness.
First when we are content with what we have, we show gratitude. Greed does not flourish in this environment. We do not need more. This can apply to money, food, affection and material wealth. We no longer need to over eat, over shop or be a workaholic. There is also a glow of humility that others can see in you.
Selfless giving To Others
As we level up in our gratitude, we become selfless. We do for others without expectations or wanting in return. Love can dwell in our hearts in a pure form. In giving to others, society can thrive and flourish. The world is healthy.
Gratitude to God is the highest form of gratitude. He has given us life and air to breathe. Taking time daily to say 'thank you' daily through your actions and words is pure and good. It offers a returned balance to compliment God's love. I believe this is the highest level of gratitude.
As we examine these, they parallel the two greatest commandments as was quoted.
Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind. This is the first and great commandment. And the second is like unto it, Thou shalt love thy neighbour as thyself. On these two commandments hang all the law and the prophets. Mathew 22: 37 - 40.
May your journey through the levels bring a higher spiritual awareness and may your life be blessed.
