this is also a good time and place to dispel some myths that have become associated with buddhism.
sorry about the following disclaimers but in my experience talking about any kind of doctrine or belief system can start arguments and i do not want that so please read these next paragraphs.
all of this information is found in the pali canon which is the oldest and original teachings of the buddha. many different versions came about after the original and changed a lot of things around. if any of this doesn't agree with some other version of buddhism you know of then that is why. please keep it to yourself as i am not trying to say any versions of buddhism are wrong, they are all good in different ways, i am simply repeating what the original, oldest known teachings say. i will not answer any posts arguing about what other sect says what.
also historians, scientists, and archeologists agree that the pali canon is the oldest and are the original teachings of the buddha. i have done my research and this view is nearly unanimous in the secular world. a lot of later sects claim that their canon is the original but history, archeology and science do not support these ideas. so if you think that your version is the original good for you, there is nothing wrong with that but please keep it to yourself, i will not answer any posts about that topic.
if someone notices that i am wrong about something in direct reference to the pali canon then by all means correct me. give me the passage that proves me wrong followed by what book it came from and what chapter and verse and i will edit my post or add a post to supplement it. like if you find i'm wrong about something and you found the correct info in the samyutta nikaya section 50 verse 6 then you would post the passage and follow it with that info or shorten it to "S. 50:6". i will however not respond to any posts that just claim i'm wrong without a valid reference. my information comes from my study of the pali canon so if your information does too then that's great, however if it is just hear-say or from another source it is not directly relevant to the pali canon and i wouldn't be able to double check my information.
1. buddhism is a religion- if religion is defined as "worship, prayer, belief, ritual, magic, and/or faith in a higher power..." then buddhism is not in any way a religion as it is devoid of all of these things. there is no rule against being a buddhist and doing these things either. thus one can be any religion and also a buddhist (as long as your religion does not promote and require non-buddhist ideals such as violence or other things). some sects have turned it into a religion involving prayer, rituals, magic, belief in deities and other things, however none of these practices can be found in the original teachings. if these kinds of ideals and practices work for you that is fantastic, there is nothing wrong with them. i'm just stating what is and is not in the original teachings.
2.buddhists pray to the buddha- the buddha specifically said that he is not a god and that he should not be prayed to. he never claimed to be anything but an enlightened man. further more he made it clear that after his death he is utterly gone from any kind of existence and therefore could never affect our world(s) ever again. praying to the buddha or other buddhas is something that is done by certain sects of buddhism that use contradicting scriptures that were created long after the original buddhist teachings and are not of the same source. these sects usually have these practices because buddhism combined with their indigenous religion when it entered whatever country they lived in. in the original buddhist teachings coming directly from the buddha there is zero prayer. any sects that involve prayer to him are going against the buddha's original teachings and require a different version or completely different scriptures to justify this. any sects that pray to other "buddhas" have usually simply renamed deities from previous religions. like saying you are buddhist and that zeus is a buddha and you pray to him. this is all well and good, there is nothing wrong with going with a sect that prays to the buddha or buddhas if that works for you. i'm just stating what is and is not in the original teachings.
3.buddhists worship gods- there are a large amount of stories where the buddha transports himself to certain brahma (god) worlds simply to tell the brahmas there that they are not immortal. that they too will die and be reborn and that they need to practice buddhism to escape. the buddha taught that none of these gods are immortal. furthermore he taught that rebirth has been going on for infinite time so that means that every one of us has been a god before. so no, the buddha definitely did not teach to worship god(s). however he does not specifically say that it is forbidden.
4.buddhism is an atheistic religion- no, as i said before the buddha made it clear that gods do exist so that is not atheism regardless of whether or not these gods are immortal. he also does not say whether or not there is a supreme god or gods above all other gods, he certainly doesn't say that there is either. he talks about nibbana (sanskrit nirvana) in many metaphorical ways. frequently they are interpreted as extinction, nothingness. some of them could be taken to imply that outside of our reality and the six realms is a supreme creator god(s) inside of which all this exists and that nibbana is becoming one with such god(s). any of these inferences would be totally up to the reader as they are very, very vague and in no way directly say any of this. but since it is so vague and open these things can be assumed or rejected based on the readers preference. essentially the reader has to invent an explanation of exactly what nibbana is beyond the information about it that is clear and consistent. so frequently it sounds like nothingness but then you will come across a quote where the buddha specifically says it is not "annihilation" and so the reader has to decide what it is then. it is always described as escape from the cycle of life death and rebirth but if it's not nothingness then the next part is wide open. one common view is that an enlightened person upon reaching parinibbana (sanskrit: parinirvana) at the time of death becomes one with all the energy of the universe. so the cycle is broken and they are liberated but not annihilated either. they cease to exist in any form in the six realms but they are not completely gone either. they are never again conscious and forever one with pure energy, never to suffer again. and if someone wants to say that this is becoming one with god then it's completely open to that interpretation. so for multiple reasons it is not atheistic by definition. so once again a person can be buddhist and also whatever religion they want. he describes it in many ways and it's open to interpretation which leads to great freedom and broadness of practice.
4. buddhists are vegetarian- seriously i have no idea where this comes from. i thought the same thing as a lot of modern monks/nuns are and then i read a direct quote from the buddha saying it's perfectly fine to eat meat as long as the animal wasn't killed directly for you and you didn't see or hear it being killed. the buddha and all of his monks/nuns ate meat.
5.the buddha was a big fat guy-no, the statues depicting a big fat guy are of a person named budai who supposedly lived in china around 907 AD more than a thousand years after the buddha's death(paraphrased from wikipedia). he has nothing to do with the historical buddha other than that he was a buddhist monk. the historical buddha is siddhartha gautama who lived in india from 563-483 B.C. and early in his practice he was extremely emaciated for a few years and then for the rest of his life he was of a thin, average build. the statues you see of a thin meditating person are the historical buddha.
