I have read about the states of Jhana through Focused Attention Meditation by focusing on breath in Ajahn Brahm's book Mindfulness, Bliss and Beyond. But I find it extremely difficult to focus my attention on my breath.
Instead, I practice Open Monitoring Meditation (OMM) which I understand as mindfulness of the present moment, being aware of all the sense faculties and not reacting to them or getting carried away by thoughts. What I find most useful is to be aware of the activity in my skull or my brain. If I focus on this activity it seems to diminish. I have gotten this method by myself.
My question is, will the OMM lead to the states of Jhana? and What will be the first stage towards it?
