This is 4 feet in size and is made up off sandstone .This is a giant ashoka chakra beautifully handcrafted by the workers of Odisha.The Wheel of the Sun Gods Chariot is the same as the Dharmachakra of the Buddhists - The Wheel of Karma, The Wheel of the Law.The eight spokes of the wheel represent the eight positions of the sun as it travels around the Earth.
Each of the spokes contains a picture including sex between the King and Queen with all the astrologers around them predicting a propitious time for conception.
The sun is the outside of the wheel as it travels around the Earth. The Sun sends energy to the Earth through the spokes, as milk flows over the Shivalingam washing away all Karma, all negativity into the center of the earth.
Negativity is burnt in the nuclear fires in the center of the earth.
In the Center of the earth is the Black Sun which burns all negativity and sends the purified energy, Kundalini Energy, upwards, back towards the sun.
