Saying that one should be patient and withstand trouble doesn’t mean one should be defeated and overcome. The whole purpose of engaging in the practice of patience is to become stronger in mind, stronger in heart. And you also want to remain calm. If you lose patience and your brain becomes confused with emotion, you will lose the power to analyze and figure out how to overcome the negative force that is opposing you
The term ninja translates as patient person, not assassin or night stalker. The word and the practice are about engaging fully in life, riding the moment, and waiting for the perfect time. It is about knowing that 'good things come to those who wait' and that 'the early bird gets the worm'. With practice, you can learn to tell the difference.
By taking up a physical practice, we are able to see our emotional brain at work. We can see it get stuck, frustrated, and angry. We can also see it prevail. Ultimately, we practice self defense to learn to make our lives brighter, happier, and safer. To do that we need to discern truth clearly.
I believe it is critical to have a practice venue where we can experiment with the success and failure of engaging with truth. Otherwise it's our friends and families who have to practice patience while we try to figure it out.
