It means alot of the stuff already mentioned.
I also now feel inextricably linked to my Instructor and club. I dont think I could learn BJJ from another instructor (long term) without feeling that I had left my heart and soul behind.
Wilson, Dickie and Simon have given me the tools that I use 4 or 5 times a week. These tools defeat bigger and stronger people than me. They make me feel strong, they represent my dedication and my longing to learn an art that is technical and thoughtful. Carlson Gracie/BJJ has seeped into pretty much every aspect of my life, if I moved away from where I live my Jiujitsu and My Carlson Gracie Revolution Team purple belt will travel with me to where ever I might end up.
If I have to train on my own, fuck it, I'll be training on my own and my sit out/ sprawl and cardio will be fucking awesome. I will train infront of a lifesize portrait of Carlson with the Revolution flag under it whilst screaming OSSS during uchikomi on my grappling dummy.
I dont think that I felt this strongly when I was a blue belt. Its not an expected aspect of getting a purple belt im sure. But when Wilson gave me the belt, I felt it, and will honour it.
