Hi wisely_xu,
Thanks you so much for the great info! It is indeed very educational for me
One curious question pop up in my mind after reading your post:
Is there a reason why the deity seal must be stamped on the back of our shirt, at the topmost centre position?
Since the deity seal's mark symbolizes the divine bestowing blessings on the person, it should not matter where the seal's mark is. Having a seal's mark on the back of our shirt is very conspicuous (especially at the topmost central position) and wouldn't it be great if it can be stamped on less conspicuous part of our clothes, or even better still, stamp on our arms/hands (like those entry chops in disco/pubs) and I think the blessings we received will be even more greater because the seal's mark is directly on our body.
