This is an image of various kinds of lingas I took at the ancient of Kashi, known as Varanasi today. Varanasi is a city that is several thousands of years old. Gautama the Buddha gave his first sermon here 2500 years ago, and it was already an ancient center of learning then. Varanasi is a city of temples. There are over 33000 temples in the city. The entire city is essentially dedicated to Shiva, which is why festivals such as Mahashivratri and Guru Purnima are widely celebrated in the city.
