The tradition of praying at 9 temples in Ayutthaya is an effort to stock pile merit and luck for the rest of the year. 9 in Thai, "gao," is the same word as "gao," / progress. Many Thais go to 9 temples every January to start the year off right so that it progresses well. But being the always-positive and want-to-be-positive me, I see it as a good way to end and give thanks for the blessed year so that we can start the new year right! Thank you, Nuch. You always make time for us.
