According to the Bhagavad Gita, the who world is a Matrix, an illusionary creation of consciousness, Maya.
And to acknowledge that, there was a temple built during the period of The Mahabharata near the present Mehraoli, Delhi.
The Ancient Structure was disrupted by the invaders but was later reconstructed by King Hemachandra Vikramaditya.

Later on, during the reign of Akbar II there was a miracle took place that the Mughal royal family themselves revered this place.
The temple also signifies the Kundalini Energy, and the power of destructing ones illusions and clears the path for ones enlightenment.  

 The unique aspect about the temple was that, the descendents of a single ancestor, still maintain this temple,
which was constructed to mark Krishna’s Victory over Kansa and Honour Yoga Maya, who took Krishna’s place that led to his escape from Kansa.
An ancient Iron Cage was at display at this Temple. The Cage is 8 feet tall and 10 feet wide, that has two stone tigers in it.
