A Warrior does not sleep, a Warrior exists in various states of consciousness. Always on, always aware.
The Warrior leads a life of solitude many times. Countless hours training, refining, thinking. Should the Warrior let his/her guard down for a moment, it could be last time it happened. When you have doubts, rest assured that if you have balance, vision, and purpose, you can find courage and strength to take another step. Training and execution is your craft, your way of life. When the Warrior puts down the weapons of destruction to make peace, the Warrior must disband, because his/her original purpose for existing has been accomplished. Until that changing of the guard happens, until there is peace, until you can sleep without doubt, and act without hesitation, and know that each action of yours has a purpose, you must train. You must persist without question. There is no middle ground for this being.
The Warrior will witness and behold the power of the one who makes worlds collide, and approach without fear, ego, or malice, and ask "what can you teach me". Wearing no material armour of any sort, and purely relying on the essential experiences of the past to give rise to the events of the present moment. Utilizing one's calm mind, uncontainable spirit, to manifest the future through proper thoughts, and proper action. Needlessly shedding spiritual anchors, to be an inevitable example of strength, agility, intellect, and grace in this world.
