To be honest, I'm not really sure what I'm doing here. I generally don't do generals and I don't really know anything about the tree of life. Furthermore, I'm somewhat confused by the role of card 0. The spread instructions seem to imply it could fulfill a number of different roles, including the seemingly contradictory ones of being either an action to take in response to the other three cards or a picture of where you are at the present moment.
In any case, what we can immediately see without any shadow of a doubt is the conflict between fire vs. water / wands vs. cups. Whatever the 0 spread position ultimately means, that 8 of Wands elemental dignities would show it being suppressed by the water on either side.
So, as a general reading about your impending summer, here's what I think is going on:
The root energy is Fire/Mars/Aries and, situationally, you're Fire/Mercury/Sagittarius. These suggest that maybe you're trying to do too much, control too much, push too much. That there's some thing or things that you want to happen in your way and on your schedule. As the surrounding water shows, all of this pushing is going to be counterproductive at best. Let things flow, take some time to breathe. Understand that you have what you need and that things will likely work themselves out. The Mars connection between the 10 of Cups and the 2 of Wands makes me think that things can work out your way without you having to push so hard.
Do you think that the Prince of Cups represents another person in this situation? Fire needs air to burn. If you're trying too hard to dominate/get your way with someone you need, you may cheat yourself out of the necessary fuel you require. Yes, wings are super common in this deck, but even so, the presence of wings on all four cards make me think that everything/everyone needs to be working together harmoniously rather that you trying to force everything into your way of doing.
Thinking about the spread a little more, cards 2 and 3 come out of card 1. It is the energy of the 1st Sepheroth that spills down into the next two. Therefore, the water that is suppressing you/the 8 is a result of the 2 of Wands
ETA: It looks like my last several lines got deleted somehow. IIRC, it was an explantion of why I interpreted it the way I did rather than saying that your 8 of Wands self is being doused by all that water. Burn hot and dominate that sucker Prince. The water that suppresses you seems to be a result of the 2 of Wands dominating energy. Therefore, not dominating gets rid of that soggy feeling.
