what is the typical minimum duration of a meditation session?
The average guideline, for a meditation session, is 20 minutes for a minimum practice. Many advanced practitioners have longer sessions because meditation has become a rewarding experience. If you have set aside the time, the amount of time practicing is not as important as the quality of the experience. For example: If you manage to focus your mind and reach a state of awareness, the amount of time it takes is irrelevant. Twenty minutes of fidgeting and self-judgment is a waste of meditation time, but it is a lesson in patience and developing inner calm.
