How important is constancy in meditation practice? I'm going through a period of meditating every day which is not how I usually practice. Before I would meditate 5-6 times a week then deliberately not do more as I would seem to 'run dry' and lose my feeling for it and felt like a needed a gap. So I'm trying just to keep going and see how that works.

But how important is constancy in meditation? - is it better just to ease off for a day if you feel depleted with it or would the thing be to keep with it even if the practice feels dry and barren.

Many thanks as always
I'm just wondering - if you were to take an antibiotic and not feel the effects, would you lay off the medication for a couple of days?  Meditation is really no different.  Nothing is more important than the consistency of the dosage.  Some days you'll have sits where the heavens open up and angels start singing.  Other days it's a slog.  Your legs hurt, your breathing is shallow, and nothing appears to be happening.  Rest assured, however, that something always is happening.  Tectonic karmic plates are shifting slow deep underground.  Keep applying the pressure of practice and the tremors of insight will eventually rise to the surface.  If anything, those sits where you feel like you're "running dry" are the most important.  The effort that it takes to actually get your butt onto the cushion is exponentially more important than the focused bliss you feel during a good sit.  The selfless offering that you make of yourself to your practice is what makes change happen.
