Buddhism is nothing like Christianity - it is cultural. Christianity is a personal relationship.
That’s simply not true. Even a cursory glance of Zen Buddhism, the 4 noble truths and the noble eightfold path noble will tell you that.
Though I will admit that there is corrupt Buddhism. Any Buddhist that worships the Buddha or say an individual such as the Dali Lama, simply doesn’t get it.
“If you meet the Buddha on the road, Kill him”.
Is a simple message that means if you adhere to the Buddha as an icon, you won’t attain enlightenment.
Sure, there are differences ~ for funerals they may be bridged over ~ although some specific traditions can be quite different.
