The need for consistency cannot be overstated. Great energy put into the practice of when-which-how, followed by interruptions due to other activities will not lead to effective service over the long run. The moderate, middle way is a tried and tested attitude to most disciplines, especially the subtleties of psycho-spiritual practices. Setting up a schedule and doing one’s best to maintain it is very helpful. Naturally, there are always times when schedules cannot be met, but the fact that you have a schedule to return to is a tremendous advantage in staying consistent with the practice.
