There are many gold deposits in India and there are clear references in the history books. Such a huge treasure worth one billion rupees is lying in a room of 'Son Bhandar Gufa' in Rajgir village of Nalanda district of Bihar. The precious gold of King Bimbisara, the founder of the Haryaka dynasty, the emperor of the Magadha Empire, is full of many secrets.

Emperor Bimbisara (6 BC 31 BC) had a Khadirsar Bhil and another name Shreenik. Earlier he was a follower of Buddhism. In Rajgir, the ancient capital, Lord Buddha also preached to Bimbisara, but later, influenced by his wife's teachings, he converted to Jainism. King Bimbisara gained much fame by increasing the fame and honor of Magadha through marital treaties and conquests.

His first queen was Koshaladevi, the sister of King Pasenjit of Kausal. He got 1 lakh revenue village of Kashi as dowry. His second wife's name was Chellana who was the daughter of King Chetak of Vaishali. His third queen was Saudaryavati, Rupangana, Ganika Amrapali. This matter is mentioned in Jain literature. His fourth queen was Kshema (Khema) who was the princess of the soft country Kuhu. Bimbisara defeated Brahmadatta and conquered the Anga kingdom. There were 20,000 villages in the state of Bimbisara. He had so much wealth from such a vast sultanate that it was eventually hidden in this gold treasure cave chamber.

The name of the son of Emperor Bimbisara was Ajatashatru, but how can it be said that he became the enemy of his just, honest, Prajavatsav father! According to the Buddhist scripture 'Vinaya Pitak', Bimbisara had proclaimed his son Ajatashatru as Yuvraj but he killed Bimbisara with the intention of gaining power soon. He was incited by Siddhartha's cousin Devdutt to commit such a heinous act and there were many conspiracies.

According to the Jain scripture 'Essential Sutra', Ajatashatru had imprisoned his father Bimbisara with the desire to get the kingdom soon. In that captivity, Queen Chellana stayed with him and took care of him. In order to prevent Ajatashatru from taking the precious treasure of Bimbisara, Rani Chellana and Koshaladevi placed it near the nearby cave where Bimbisara was imprisoned. The remains of that prison are still there.

Then when Ajatashatru found out that his father loved him very much and had already declared him Yuvraj, he rushed to release him from captivity. He was carrying an iron rod to break his chains. Bimbisara felt that the punishment had come to kill him so he ate the poison he had and died.

The first room to enter the Son Bhandar cave is 10.6 meters long, 2.5 meters wide and 1.5 meters high. It was inhabited by soldiers and guards guarding the treasure. There is a way to reach the treasure from the back wall of the room, the door of which is closed by a stone door. The mystery begins here. Since the gate was closed thousands of years ago, no one has been able to open it, neither the enemy and its army, nor its descendants, nor the robbers or the British army - anyone has been able to open it.

It would not have collapsed if cannonballs had been fired at it to break down the cave and its wall. It still bears the marks of a cannonball fired by the British. Dynamite was also thought to have been blown up, but in 1908 Lord Durz passed a bill forbidding it. The cave has many natural springs of water. It was banned because of the large explosions caused by the sulfur etc. in the soil.

There is an entrance to the Son Bhandar and a mysterious inscription has been inscribed on the wall. Bimbisara and the queens feared that the gold treasure kept in the second back room of the cave would be looted, so they secured the stone gate with the help of their magician-learned guru. Rani Chellana called Jain Muni Vairadeva and Maharani Koshladevi called Jain Muni Gautam and closed the door with a mantra. Which was arranged to be opened only by the secret code of the mantra sound.

This mantra sound acts as a password. It is said that the door can be opened only if the mantra is sung with the pronunciation of yoga ascent and descent. What is the mantra in the conch inscription is indicated on the wall. But this script is extremely mysterious. No one has been able to solve it yet.

Nalanda University in Magadha had three very large libraries named Ratna, Dhan, Ratnasagar, and Ratnodadhi. It contained millions of rare books. The three libraries were set on fire in 115 AD by a Turkish ruler named Muhammad bin Lakhtia Rakhilji. It is said that the fire was not extinguished for three months. One can imagine how many books it will contain. These libraries also contained books of mysterious cryptography but after it was burnt, no one could find out what was the cardword or password form mantra on the cave wall. So that door could never be opened by anyone. The idols of Jain pilgrims have been installed. Some people also believe that the way to reach this treasure is from Vaibhavgiri mountain, Sagar to Sapatparna caves which reach to the other side of Sonbhandar cave. But no one could go to the cave from there!
