In Discourses on Satipatthana Sutta, S. N. Goenka mentions a similar symbolism on how the pagoda relates to the Maha Satipatthana Sutta:
In every chapter the repetition of certain words indicates the importance of this sampajañña. Ātāpī sampajāno satimā applies to the observation of kāya, vedanā, citta and dhammā: sampajañña has to be present. Similarly samudaya-, vaya-, and samudaya-vaya-dhammānupassī, which apply everywhere in the Sutta, have to be with sampajañña and sensations. For example, in Myanmar there are many pagodas on plateaus, with four staircases, one each from the east, west, north and south. Similarly you might start with kāya, vedanā, citta, or dhammā, but as you enter the gallery they all intermingle in vedanā, and reaching the shrine room it is the same nibbāna. Whichever staircase you start climbing, you come to vedanā and sampajañña: and if you are with sampajañña you are progressing step by step towards the final goal.
Are there any other forms of symbolism regarding pagodas and the Maha Sattipattana Sutta and other suttas covering Samatha meditation subjects?
