I just want to share an experience of mine that has given me the discipline I needed to have a daily practice. I'm a lazy person, so for me to have a daily practice was always a nightmare. But I discovered the trick. Instead of aiming at sitting for 20, 30 or 60 minutes doing meditation, I said to myself: "well, I'll try doing walking meditation instead". So the trick is to be mindful in the time periods you're doing routine tasks that you would otherwise be doing with some aversion. For example, to go to the university I walk a good distance and take the subway. So I use that period to do walking meditation and, when I'm still, in the subway, doing mindfulness of the breath.
Not only is this beneficial in itself, because I end up cultivating my mind, but it also has the wonderful side effect of me having the discipline to sit for 30 minutes doing samatha. It's a win-win situation: time is not wasted, I practice mindfulness and on top of that it's much more likely that I sit to do meditation.
Simple, huh? Try it!
He turns his mind away from those phenomena, and having done so, inclines his mind to the property of deathlessness: 'This is peace, this is exquisite — the resolution of all fabrications; the relinquishment of all acquisitions; the ending of craving; dispassion; cessation; Unbinding.'
