Over the years many students coming to a Master Support Session have chosen to book in a Massage with the Master while they're there. Some Supervising Masters even offer a special "Master Support Session + Massage" combo price. It's a great way to make the most of your travel time.
Generally the Massage will happen after the Master Support Session so you're fully "in the groove" for the learning and can then let go as much as you want in the treatment. Alternatively, if you're staying overnight you may choose to have your Massage on arrival, and then your Master Support Session the next morning - the overnight giving you chance to "reset" to learn in the morning.
