A real practice

You can see that there is nothing more down to earth than Buddhist practice. If there are some Buddhists who do rituals (offering flowers to a statue, praying spirits, making signs in a certain way thinking that this will bring luck...), that means that they do not understand what is the Buddhist practice, because Buddha has well explained that these things are vain.
That's why it is very important to understand precisely what you do, to practice what you can check yourself, and to not practice something just because everybody does it all around you or because you are told " That's the way to do it".
