I will start the ball rolling with
1) when you are about to enter the temple grounds, or entrances of the shrine hall that has 3 openings, left, center, right, go in from the left of the temple, meaning, if you are in the temple facing outwards, the left.
Traditional Chinese thinking is that the left is the Dragon side, right is the Tiger side.
Never enter from the center because that is for the "holy beings" or the monks.
2) For the prayer cushion, don't pray at the center, take the left or right of it. It's not for us, it's for the monks conducting the prayer rituals.
I don't know why these are not really shared nowadays, so thought of sharing some of these. More to share in next few posts such as
1) rotating the charms we have around the incense burner 3 times clockwise
2) walking around holy objects/beings 3 times clockwise.
3) don't lean on pillars
