Re: Died while practicing aikido?
My condolences. I've been to Cebu a few times. It really is a blessing to pass away in the area that you spend a lot of time on, doing what you love. Saints died while helping or doing doing charity. At least he died happy.
I share your loss too. Not too many make it to 4th dan. Maybe this can also be an inspiration for you to keep continuing your practice in memory of your friend.
