I know this is an older thread, but thought I'd throw some more information into it.

did anyone else notice the ARROW between the first two cups on the ground? I never noticed it before. It points towards the steps and the area where the "guard" is walking. Also, the FIRST cup (on the ground) has a flower pointing backwards, so...I think Pamela Colman Smith was trying to get our attention on the guard....or the "going back" thing.
When I see this card I DO think about the past...and innocent, helpful, loving (non-sexual) compassion...the thing we're probably born with before we get distracted in this overly-competitive, commercial world.
I see the two main characters as friends...or perhaps brother and sister....with the older of the two bending at the knee to compassionately allow the younger of the two to smell the flowers. The older child is being kind and considerate to the younger child....helpful and compassionate.
I just took another look and never noticed that both children are wearing the same type of hood. The girl's is harder to discern as having that long "tail," but you can see a gap at the back of her head.
Hmmmm...looking again...I may see at least one other arrow. Does anyone see an arrow just under the left corner of the cup the boy is holding? It's pointing downward. Now, I may just be reading into this too much, but it looks like the word "YODS" is spelled out in the greenery just under that arrow. Does anyone else see it? Or an "RWS" (?) on the ground in-between the 2nd and 3rd cups?
Anyway...just thought I'd add my two cents on this thread.
