Buddhist Teachings That Will Make Your Life A Happier One:

1. Anitya – Impermanence.
We aren’t permanent. Nor is anything else in this world. Things change every day. Each day, our bodies are different, our environment is different – our whole universe is different!
Celebrate the idea that our lives change every day. Accept this constantly moving existence. When you look at it through new eyes, it’s pretty exciting, isn’t it! Each new day brings new opportunities.

2. Dukkha – Life is suffering.
This one sounds kind of negative, doesn’t it? But it’s not just trying to tell you that life is tough and you need to buck up, but that attachment to people, things, and expectations is a cause of pain. Try not to buy into the idea that you’re a broken person. Expect that your body will decay over time and that strife will happen and you’ll be more resilient in the face of it.

3. Anatma – Life is constantly changing.
Buddhism doesn’t assume that there is a fixed self, but rather, a constantly changing self. Our thoughts, names, jobs, titles, and even personalities identify us, but those things can change overtime. As Thich Nhat Hanh says, “Thanks to impermanence, anything is possible.”
Instead of trying to find yourself, focus on creating yourself. Create the best possible self for this moment. Worry about the kind of self you need to be for tomorrow tomorrow. Focus on the you you want to be now.
