Wow haha, I have definitely felt just like that big guy! Thats pretty much perfect, great find Mew!
I'm so happy that other people feel this way on cactus! I've only had one real cactus experience and I thought it may have been a one time thing for me and that was sort of sad. I kept telling my wife that I felt "clear" but couldn't express it in a way that made sense.
I hope you are referring to the big guy when you say it reminded you of the cactus spirit...
