I have always felt this an equal to the two of pentacles. I agree with all that everyone else has said on this card and I think we've got it fairly well defined. To add a bit, here is some of my thoughts I've held for this card. Of course it all depends on what aspects its wanting to emphasize at the moment. Yes, this is all about controlled balance and hopefully staying in the ability to do so and be calm.
If you think of this as a concert with an orchestra. They perform like a fine oiled machine. This card is about precision as well. I remember the name of this card from Brian was "The Dressing of a Salad" and when Jesa worked with it, it became "The Undressing of a Salad". I wonder if the Fae were attempting to show what we would think of perhap a reverse card situation of Brian's view of it. Back to the orchestra, image they are coming to your city and the time that they are to perform there is a nasty flu going around and several of the members were hit with it. Rather than cancelling they rush in people of different skill levels to fill in for those sick. This is last minute and there is no time to do a run through of the music. How balanced do you think the orchestra would be? A measure or two behind, off-key....bad news. You may try covering up, but a good ear would discern it and yuck. Thus your undressing of the salad lol.
Thing of the busy three ring circus. This card makes me see this too. All three rings know exactly their routine and the timing of it in regards to the other rings. As excited as a child (and adults) may be, you cannot view all three rings at the same time to any degree of satisfaction and with fully taking it what is being done. Look at how this situation speaks of balance. Balance of each performer and the viewer having to balance watching one ring and changing to view a different ring as trying not to miss much. Its hard to keep calm and balance with excess, (a lesson this card is telling). I feel this is where the undressing is coming in. Too much and it says, lets undress this a bit, after all even with jugglers there is a point where there is too much in the air to keep up with maintaining the juggling.
Lastly if you cook, bake, or work with spices and herbs and as this card reflects work to make a perfect salad, you want to orchestrate a complimentary blend. You do not want one to be over-powering as it tilts the balance. Try removing that! Start with a different salad, sure you can toss a bunch of greens in and other salad fixings, toss on some bottled dressing and enjoy it. However if you have a fresh made dressing with fresh herbs and a variety of ingredients for the salad itself, if blended with the right balance it is a masterpiece! Even if you aren't of chef material you know the difference of a fast food salad and then some of the up-scale places how unique some of these places their salads are. Yum! Oh by the way, I once ordered a salad with one dressing and it was the wrong one, so sent it back. Guess what?! This waitress attempted to "undress the salad" LOL. It was most unsuccessful! We called to a different waitress other than our own and I eventually had a salad that I had ordered. Bet the owner had a talk with the first waitress. Makes for bad business, I haven't been back.
