James Hilton wrote about this mystical city in 1933 in his book "Lost Horizon". Hollywood then picked it up in the 1960 film, "Shangri-la". Even the famous author James Redfield wrote The Celestine Prophecy also wrote a book entitled "The Secret of Shambala: In Search of the Eleven Insight." The mysterious Shambhala is also considered as a source for the Kalachakra, which is high and most esoteric branch of Tibetan mysticism.

Legend of Shambhala has existed since thousands of years ago. We can find a record of this kingdom in ancient texts such as the Kalachakra and Zhang Zhung that even existed before Buddhism entered Tibet.
The word Shambala (or Shambala) is derived from Sanskrit which means "Place of peace" or "Place of silence". This kingdom has a capital named Kalapa and ruled by the kings of the dynasty Kulika or Kalki. This is where living things are perfect and semi perfect meet and jointly guide the evolution of humanity. Only those who are pure in heart that can live in this place. There they will enjoy happiness and peace and will not even recognize the suffering.
It is said that in the kingdom, love and kebijakanlah ruling. It never occurred injustice. Its people have a very deep spiritual knowledge and culture they are constituted by law, art and knowledge are far higher than ever achieved by the attainment of the outside world.
Many adventurers and explorers have been trying to find this mystical kingdom. According to them, may Shambala is located in the mountainous regions of Eurasia, hidden from the outside world. Others who do not find it to believe that Shambala is just a symbol, a liaison between the real world with a world that existed beyond. But, some people longer believe that Shambhala is a real world.
According to Zhang Zhung ancient text, Shambhala is identical to the Sutlej Valley in Himachal Pradesh. While the nation Mongolia identified it with certain valleys of southern Siberia.

Information about this kingdom up to the western civilization the first time through a Portuguese Catholic missionary named Estevao Cacella who heard this story from the locals. Then in 1833, a Hungarian scholar named Corrosion Csoma Sandor even providing coordinates of Shambhala is believed to be between 45 'and 50' north latitude.
Interestingly, according to records Alexandra David Neel who has spent most of his life in Tibet, Shambala was not only known in Tibet. Far in the north of Afghanistan, there is a small town called Balkh, an ancient city which is also known as the "mother of cities". Legend states that the modern Afghan society after the conquest by the Muslims, the city of Balkh is often referred to as a "wax up" or in Persian called "Sham-i-Bala". I do not know, we do not know for sure whether the city is associated with a mysterious Shambhala or not.

Legend of Shambhala then drew the attention of a follower of esoteric and theosophy named Nicholas Roerich (1874-1947). In curiosity, he explored the Gobi desert to the mountains of Altai from 1923 until 1928. This trip travel 15,500 miles and crossed the 35 highest mountain peaks in the world. But the tremendous effort it still can not find the kingdom.
Even the Nazis are also highly related to the esoteric world of Shambhala've sent a search expedition in 1930, 1934 and 1938.
But, none of them who managed to find it.
Edwin Bernbaum writes in "The Way of Shambhala":

"While the explorers approached the kingdom, their journey becomes increasingly difficult to see. One of the Tibetan priest wrote that this event was intended to keep Shambhala from the barbarians who intend to master it."

What was written by Bernbaum is closely associated with the prediction of Shambhala. According to the prophecy, humanity will experience a degradation of ideology and humanity. Materialism will spread throughout the earth. When the "barbarians" are united under the command of a wicked king, only then can the fog that envelops the mountains of Shambhala would be lifted and the king's army with terrible weapons to attack the city.
Then the king of Shambhala to-25 named Rudra Cakrin will lead his troops to fight the barbarians it. In that battle, the evil king and his troops successfully destroyed and mankind will be restored to the peace.
Some scholars such as Alex Berzin, using calculations from the Kalachakra Tantra, believed that these events will occur in the year 2424 AD.
As culture moves east to west, rise from the Shambhala myth in the mists of time. I think, longing for kedamaianlah which has caused mankind to try to find this utopian kingdom. Maybe we'll never find Shambhala, but maybe we also need not look too far.
An ancient tale from Tibet told that one day there was a young man preparing to search for Shambhala. After exploring the many mountains, he found a cave. Inside was an old hermit who then asked the young man: "Where your goals so that you are willing to explore this deep snow?"
"To find Shambhala," replied the young man.
"Ah, you do not have to go far." Said the hermit. "Behold the kingdom of Shambhala is in your own heart."
Is there really a Shambhala in our hearts?
