Today, Memorial Day, is a good day to remember that it has been the warrior class that was entrusted with the Knowledge throughout the ages. Note that Lord Krishna was a kshatriya (warrior).
Principles like duty, honor, trust, and loyalty are upheld by the military. This is so even while those principles may be somewhat out of favor with many. It is said that the valorous, who fall in battle, immediately attain moksha.
To live a life dedicated to something greater than the small ‘personality’ self is a great thing. I for one will take this day to humbly honor the valorous.
