Did geography affect the spread of buddhism?

so the answer is YES

Explanation:

Although Buddhism spread throughout Asia it remained virtually unknown in the West until modern times. The early missions sent by the emperor Ashoka to the West did not bear fruit.

Knowledge of Buddhism has come through three main channels: Western scholars; the work of philosophers, writers and artists; and the arrival of Asian immigrants who have brought various forms of Buddhism with them to Europe, North America and Australia.

The 'come and see for yourself' attitude of Buddhism attracts many Westerners. They are not asked to believe in anything, but to follow the Buddha's advice of testing ideas first.

With the growth of easy travel and communications, the West has been able to find out more about Buddhism in this century than in all the time before. The informality and emphasis on practice of Buddhism appeals to many Westerners.
