How can we explain the fall of Buddhism in India, which is the geographic origin of Buddhism?
Were there ever any direct conflicts between Hinduism and Buddhism?
From what I understand, the rise of Hinduism directly led to the decline of Buddhism. The White Hun invasion in the 6th century followed by a series of other military invasions and conflicts definitely hurt the influence of Buddhism but these events seem disjoint and regionally limited.
From wikipedia, what exactly does this mean? I am not satisfied with this explanation because Buddhism is strongly rooted in other Asian societies.
"By that time, Buddhism had become especially vulnerable to hostile rulers because it lacked strong roots in society as most of its adherents were ascetic communities."
