Mindfulness meditation is one way to practice mindfulness, but since being mindful simply involves paying attention to the present moment, mindfulness can be brought to anything you do. Becoming more mindful takes practice, and mindfulness meditation is good tool to learn to be more mindful.
Mindfulness and mindfulness meditation are an important part of many Buddhist traditions, but there is nothing exclusively Buddhist about mindfulness. Many other religious and spiritual practices involve mindfulness, and you can learn mindfulness and realize its benefits regardless of your religious or spiritual beliefs.
Many people try meditation and find it impossible to keep their mind from wandering and believe that becoming more mindful is something they will never be able to do. But becoming more mindful does not need to involve meditation, and mindfulness does not involve emptying your mind.
Mindfulness simply involves paying attention to whatever is going on in the present moment, and learning to bring your mind back to the present whenever you notice it wandering.
Since mindfulness simply involves paying attention to whatever is going on in the present moment, you can bring mindfulness to any aspect of your life. The formal way to practice mindfulness is through meditation, which involves paying attention to things such as your breath, physical sensations, your thoughts and your emotions.
