Gyanganj, The City Of Immortal Beings Of The Himalayas
Himalayas have always been linked to mysteries because of its futile terrain and inhabitable climate. But the myth has it that the world’s mightiest mountain range is a home to Gyanganj—a city of immortals and enlightened beings. Ancient Indian and Tibetan tales say that this place is city of mysterious immortal beings that cannot be discovered by ordinary men. It also said that the city is so well camouflaged that no modern mapping technique can identify the place. It is said that it is a place of serenity and ultimate knowledge. Fostering the belief is the famous Indian god-man called Sai Kaka Guru. He once mentioned in a meeting that “I have been to Gyanganj several times over the past half decade.” Many sadhus and mahatmas claim that their arcane knowledge stems from Gyanganj.

The 1600 Years Old Rust Free Iron Pillar of Delhi
The Iron Pillar of Delhi is famous throughout India. But one thing that most people don’t know about it is that, it is 99 per cent resistant to corrosion. The 7-feet-tall structure is as much as 1600 years old and still stands completely rust-free. Made from 98 per cent wrought iron, the pillar has been a subject of varied scientific studies from around the world. While a study concluded that critical corrosion-resistance agent called iron hydrogen phosphate hydrate makes the pillar resistant to rusting. The question that remains that how was such a chemically advanced agent manufactured almost 2000 years ago.
