There is an Ancient Parable of a Young Monk's Training while staying at The Shaolin Temple Monastery. It's a Monk's Final Test Of Courage before a Monk Pupil becomes a Master Teacher, and Becomes Proven to Be Able to leave the Shaolin Temple Monastery Grounds as a Master of Kung-Fu. 
   The Legend is that there are 2 Doors at The Shaolin Temple Monastery. 1 Door is the Side Door, where Entry and Exit from The Shaolin Temple is used to arrive and leave the Monastery Grounds by anyone, and One Door is the Open Main Door, the One that only a Master has the Permission through The Buddha to use. Before a Monk is able to use the Open Main Door, One must first Prove One's Self in One's Mastery Of The Martial Arts. Within The Shaolin Temple is a Labyrinth filled with Elemental Chaos and Order, Field Tests Of Mortal Combat and Immortal Regeneration, and Dreams and Mystic Visions Of A Utopia Land, and Nightmares and Environmental Tapestry Experiences of a NetherRealm Shores-Of-Hell Land. The Crystal Labyrinth Astral Land of The Buddha's Mind-Soul, Where The Young Monk Dwells, will bring Experiences of Spiritual and Physical Battles of Combat both Immortal and Mortal, Trials and Tribulations of Judgements with Deep Mass Scrutiny of Life's-and-Death's Understandings of One's Place and Role in the Universe, with Profound Philosophical Concepts Of Unbounded Mathematical and Numerological Intelligence and Wildly SuperNatural Spiritual Epiphanies Of Alien Societies and Genealogy of D.N.A. . These Bring True Reflections Of ManKind's Humanity and What It Means To The Buddhist Monk To Be Alive and To Die. 
   The Danger of Traps Sharpen the Monk's Senses of The Martial Arts to Refine The Character of The Individual, and Bring Deeper Definition To What Is Good and What Is Evil. The Living Universe and the Dying Soul Of The Warrior Create A Conflicted Manifestation In a Strange Mirrored World Of The Self In Deeper Reflections Of Time / Mind / Space, The Art Of War, and the Universal Dimensions of Depth, Space, Breadth, Time, and Length. With Love and Peace Always In The Young Monk's Lotus Blossoming Heart, Mind, and Body, (That-Which-Make-Up-The-Soul through The Elemental Ingredients Being Conjured, Cooked, and Animated Into Life-Being-Lived as the Dharma of Actual Self- Experienced Phenomenon), The Forces Of Nature (Yin & Yang) Are Explosively and Intimately Expressed and Self-Experienced through the Deep Multi-Dimensional Realm Of The Omnipotent Sentient Being and the Indivisible Unity of The Supreme Ultimate Being, 
    Through the Revelations and Epiphanies, Beyond Reflective Ruminations, Within the Meditation of The Labyrinth of The Shaolin Temple, The Young Monk, using One's Kung-Fu Skills, finally Approaches the Open Main Door with One final arduous Task: To OverCome The Grim Reality Of Death and Mortality, and Lift The Symbolic Urn that Blocks the Master Warrior from One's Journey Forward Beyond The Door / Gates. The Urn is Smoldering Iron, the Weight is difficult to OverCome, and there are Two Dragons Carved and Burning with Smoke Fumes from opposite sides. As The Young Warrior Monk inevitably Confronts the Obstacle, the 2 Dragons Burn and Scar the Flesh on Each Arm of the One Who Lifts the Urn out of The Way. The Distinguished Mark of the Two Dragons on The Arms decorate the Buddhist Monk as a Priest-Warrior Of Shaolin, and a Master Of The Martial Arts. 

   OverComing The Deceptive Reality Of Maya, The Buddhist Devotee Transcends the Fear Of Djinn Demons with his Kung-Fu Magick Sorcery, Accepts The Light Of The Angels and Deities In Wisdom and Knowledge, and Becomes (through Perseverance of Dignity through Humiliation and Mortification, and Tempered through Transcendental Meditation), a Dragon of The Supreme Ultimate, TAIJI, and Lives With The Three Dragons Alive In One's HeadBand...For Honor, Duty, and Respect To The Buddha, The Supreme Ultimate, and The AUM.
