...St Augustine wrote "love, and then do whatever you want".
We could say: "Practice a lot, nearly in whatever way you want".
Amen to that! I think an important componant to this kind of thinking is the idea of mindfulness. To my mind, love and sincerity are very closely related, and I tend to think as long as we have our "first step" firmly rooted in that, everything else follows fairly naturally.
I think it when it comes to repetition, it's very easy to shut off the attention, and that's problematic...1000 bad habits done are harder to reverse, but when we really work on doing everything with the utmost sincerity, those 1000 repetitions aren't pure repetition. That is to say, they appear that way externally, but internally it's a 1000 different things because each one is a unique effort.
