Sarnath is a world-famous historical site known for the ‘Dhammacakkappavattana Sutta’. This is the place where Gautama Buddha after attaining enlightenment gave his first sermon called the ‘Dhammacakkappavattana Sutta’. He preached ‘Dhamma’ to his five former companions who later turned into his disciples. The Four Noble Truths of the Sutta formed the basis of the ideology of Buddhism. From here onwards did Buddhism spread across the world.
