I knew about this but the video confirmed it.
Aum is the Symbol of the Mother of All Principles - on which all known Laws of Nature rest on.
This is why the symbol "3" or "Snake" is also found in all Civilizations.
It is the Sum Principle - the Union and Creation Principle, the Ying-Yang, the North-South Poles, the Positive-Negative principle, found in all aspects of the Reality.
It is represented as the Shiva-Shakti-(and Ganesh), the Lingam-Yoni, the Sun-Moon-(and the Earth), Father-Mother-Child, the Brahman-Maaya, the Purusha-Prakarti, and the part of Judaic Tetragammation (which goes back to Proto Indo European), as the Tree of Life, the Star of David, the Cross, the Swastika or the Auspicious Cycle of Regeneration, etc. principle.
It literally represents the union of the two sexes and the product of it. The "3" is the Feminine Symbol, the "Tail" or the "symbol for long vowel U" in Sanskrit is the Masculine Symbol, and the "Eye", the "Dot", or the "Chandra (Moon) Bindu (Dot)" in Sanskrit, is the "Dotting" Child and its symbol - the "Moon" Of Our Eyes.
What can be the most sacred to the Humanity, and rest of the Flora and Fauna but the survival of Life on the Planet - and the Planet itself? But today Humanity in name of Extreme Capitalism, World Domination by a few Rich and Powerful Nations, Race, Religion, etc. and Colon-ism has forgotten this aspect, and exploiting the Nature's resources.
How long the Oil, the Gold, the Aluminium, the Forest, etc. would last? What would happen to the empty space created in ever growing underground mines and drilled out oil-reserved-spaces in terms of structural soundness for the inhabitation om the earth's surface? What would happen if the Ice Age or World Wide Deluge happens because of Green House effect and Global Warming? Where would Humans dwell?
Is this the Inheritance we want to give to our children?
BTW, AUM Sound is the Sum Sound Human Beings can articulate or hear. The 'A' is Guttaral, from base of Stomach or Guts (that is why it is called Guttural), the 'U' is Labial and the 'M' is the Nasalized Vowel. The sum sound energy created has to resonate from the bottom most part of the body's air cavity to the top most part of the air cavity. Please note all are vowels and in Sanskrit (or even Greek or PIE Languages) without vowels, the rule is that Consonants do not make any sounds until they are combined with Vowels. The North Eastern India, Tibet, China and Mongolian people make the sound of "HUN", which is a related sound, and that is why these people by the PIE folks were called Huns.
In terms of consciousness manifestation (what is life without that), it symbolizes the Waking State, the Dream State, and the Deep Sleep State - and the Absolute or Turiya is the Summom Bonum of the Consciousness. This is why Number 3 is represented in script to symbolize three.
The number 3 also represents the three States of the Matter, the Gross/Tamaasic/Black/Iron, the Subtle/Rajaasic/Bronze Color/Bronze, and the Causal/Saatavic/White Color - as mere symbolism to convey the concepts of levels of Evolution of the Creative Nature.
