The word Pride relates to your training in two ways.
#1 - a feeling or deep pleasure or satisfaction derived from one's own achievements, the achievements of those with whom one is closely associated, or from qualities or possessions that are widely admired.
#2 - a group of lions forming a social unit.
The Lion is the king of the jungle so it's fitting you display the lion on your gear. Our sparring partners are also lions so we're also acknowledging we belong to something bigger than ourselves.
