I am currently being instructed in Samantha meditation at a local group in Belfast. As tonight is only the third meeting I'll have attended I haven't really developed that far with it.
The first week I was told "Breathe in slowly and deeply, counting from 1 to 9 then breathe out slowly and gently counting from 9 to one". Always being mindful (different, I feel from focussing) on the breath. If I find my mind wandering, acknowledge the thought and gently come back to the breath. This first week I was asked to try for maybe about 5 minutes.
The second week (last week) I was instructed to do the first weeks practice, and then after about 5 minutes of longest breathing (the 1-9 in and 9-1 out) move on to longer breathing (in 1-6 and out 6-1) for another 5 minutes or so.
I will attend class the third tonight
I enjoy it, so far, but do find that the mind is, as described by wiser men than mem like a naughty child
