The outer ring symbolises the Assamese traditional hat while the the path and the wheel with the different Province initials represents the theme of the Congress (Salesians, be Holy) intending to mean that we are all on the journey to holiness. And of course, the structure in the lower portion is the Church (I guess, of Sohra).
It has been designed by Br Dianetious (ING) with support from friends and well-wishers. If approved by all the members this could be the optical point of reference for the upcoming Congress. Thanks Br Dianetious!
