Thanks Tommy.
I've been doing this practice (or something very similar) for a few months now when walking. I start to notice that seeing is happening, then touching is happening, then hearing is happening, then that the body is moving through space... then all at once. It's evolved a bit since I first started to do it in the spring this year. Right now my main issue is remembering to be mindful of
anything during my working day and family life, but when I can it works like this:
Awareness of the breath (basic level)
Awareness of body sensations (with breath as fallback. touch of clothes on skin, wind, pain, subtle vibrations, postures)
Awareness at all sense doors (with awareness of the body as fallback)
When it's good, little insights tend to pop up and the general feeling is one of lightness of being and satisfaction with the world. It's a nice practice
