You will investigate existence itself, and see if there is anything within existence that doesn't change. Whether anything within existence can provide such lasting happiness that you are afraid to lose it, and whether there is a little man or woman behind your body and mind, a self that experiences existence. Or is there only mind? Then you will rest again by concentrating your mind. You will concentrate the mind until the mind transcends itself with a shift in consciousness where you will let go of body and mind together, all in one brief release. Then the discernment and wisdom will be automatic. Regardless of what you see in the world, there will be the reality of its impermanence, the reality of its stress, and a reality from the freedom from ego that allows you to become a true warrior. All of this requires training, however, physical and mental training. It requires faith, determination, vision, mindfulness, effort, and wisdom. But the rewards are great; a thirst for truth and a disregard for falsity that creates boundless joy, unlimited energy, tranquility in the face of danger, equanimity when faced with adversity, a focused, concentrated mind, a heightened awareness. And the courage of a lion.
