The formal aspects of Buddhist practice – the things you can look at and identify as "Buddhist practice" – are very important. These include meditation, Dharma study, and time with Sangha. However, unless you're a monk in a really strict monastery, over 90% of your time is spent outside of formal practice. It's important to remember that practice each and every moment – how we choose to live our life, just as it is – is the most important thing.
