Do Preliminary Practices?

i think that one of the things that happens early on to people who are ing is that they don't really concentrate well enough to do some of the techniques that are offered to them. And because they are not actually able to do them, you know, most of their experience of meditation is not being able to do the technique very well and not getting much out of it. So it is useful to consider doing the preliminary practices. We we, of course, in the west, particularly in america, i think, vastly overestimate our capacities and think that why should need to do preliminary practices?
