“There are no gods in Buddhism.”
“Buddhists don't believe in heaven or hell.”
These are some of the statements you typically hear in the West from people who either practice a Westernized form of Buddhism (consciously redesigned to be more acceptable to modern Westerners) or who are generally friendly to Buddhism but do not practice it. All of these statements are also false. They are basically just part of a marketing campaign to make Buddhism into something that anti-religious Western bohemians and intellectuals will find appealing. The reality of Buddhist practice in Asia is very different.
