Various express trains ply between Bhopal and cities like Delhi, Mumbai, Agra, Gwalior, Jhansi and Ujjain.
One can reach Bhopal by train and avail a bus / car from there for Sanchi.
In the past, Mahayana Buddhism also spread to other South and Southeast Asian such as the Afghanistan, Maldives, Pakistan, Sri Lanka, Burma, Cambodia, Thailand, Laos, Iran and other Central Asian countries before being replaced by Theravada Buddhism or other religions.
The Stupas of Sanchi were constructed on the orders of Emperor Ashoka to preserve and spread the Buddhist philosophy.
Sanchi has been protecting these beautiful and sacred architectural wonders, just the way these wonders have been safeguarding ancient history and art of the Mauryan period.
According to the teachings of Mahāyāna traditions, "Mahāyāna" also refers to the path of the Bodhisattva seeking complete enlightenment for the benefit of all sentient beings, also called "Bodhisattvayāna", or the "Bodhisattva Vehicle".
A bodhisattva who has accomplished this goal is called a samyaksaṃbuddha, or "fully enlightened Buddha".
