Let's say I have one hour at hand, and want to study a sutra. Should I first read 20 minutes, then reflect 20 minuts and then meditate 20 minutes? Or is it better to furst study/read the whole sutra in one or more sessions, then reflect for a similar amount of time and then the same with meditation?
The order and structure of your personal practice is not so important. It's not the amount of time you spend reading something, or whatever benefit you receive from your study and meditation. Those things are very small importance.
But.. how do you use
this in your daily life, in your relationships with others? How do you use this to benefit all beings.
I suggest focusing more in that direction. Then you really can't go wrong, whatever structure you choose for your study and practice.
