Taking a day off doesn't make much sense to the practitioner who carries everything onto the path. It's not that you don't have days that are more of a struggle than others, you do. You have good days and rough days, days that are long and days that are pure joy.
But you never have a day off, what would you choose to exclude?
Watch your negative emotions. Be cautious with your judgement and perception. Don't hold onto anything too tight. Be grateful that you have this opportunity.
