Answer this question to the best of your ability:
How do I know when I'm ready to move on to the next stage in breath control during meditation?
You should only proceed to the next stage in breath control during meditation once you have met specific requirements for each stage. For example, in Stage 3 (Stay with the breath), you must have a stable and deep state of concentration, with few distractions, lasting at least 5 minutes continuously before moving on to Stage 4 (Still the body). It's essential to take your time and ensure that you have mastered each stage before progressing to the next one.
