A Pilgrim's Diary
One of the best ways to prepare for your pilgrimage is to read accounts of past pilgrims who have taken a similar trip. While there is much literature out there on spiritual pilgrimages of all kinds, there is little such reading pertaining to Burmese Buddhist sites. Thankfully, on two previous trips run by Myanmar Pilgrimage's guides, meditators kept detailed journals about their days. These can be read in full here.
For inspiration and information, take a look at their diaries as you plan for your own Dhamma excursion.
