What are the steps in Mindfulness of Breathing meditation? I would like to have a detailed list of the steps in Mindfulness of Breathing meditation. 

What is a good suggested duration?
Steps differ by every teaching lineage. But a basic outline would look like this:


Focus on the breath and recognize it as breath, without the thought, this is me, this is mine, this is what I am, this is good, this is bad, etc.
If the mind wanders from the breath, acknowledge the thought in some system of categorizing objects that arise in the experience. The Satipatthana Sutta outlines a neat and tidy system for categorizing such objects.
Return to focusing on the breath.
Repeat 1-3 for duration of practice.


As for duration of practice, do what your body and mind can handle, and work upwards from there. Start with 5 minutes, and if that's easy, try 10 or 15. Try 30 or 60 minutes. But there's no substitute for having a teacher.

On a meditation course, my teacher had me practice 50 minutes of walking meditation, then 50 minutes of sitting meditation, repeating indefinitely. Back in the ordinary world I tend to keep it at 30 minutes (15 walking, 15 sitting).

If you study under a teacher, you will find that every teaching lineage has their own specific steps. For example in the Mahasi Sayadaw school we don't just focus on the breath. We start with rising and falling of the abdomen, and then as skill develops we include recognition of sitting, and then recognition of various points on the body. Out of respect for the teachers I don't want to go into too much detail as I am not a meditation teacher, just a practitioner.
