The difficult part of having a spiritual practice is not the practice itself; that is a joy and a blessing. The hard part is figuring out how to included everything else, how to integrate the practice with the rest of your life.
The hard part is not trying to exclude resistance, problems, pain and defeat from your practice.
In order to overcome the hard part, you need an example; fortunately or unfortunately, you need to be that example. To be the example, you'll need a strong practice; one that allows you to bring all negative situations and problems onto your path.
To be the example, you will need to master your practice.
