By the way, all the sects are primarily the same. except some are mystical and some are not. Theravada Buddhists only believe in what the Buddha taught, how to escape suffering and gain enlightenment. After that people started adding different things, like the concept of rebirth which came from Hindu religion. Zen buddhism is a mixture of the buddha's teachings and lao tse who is the father of Taoism.

but honestly, if you read what the Buddha taught, that's all you need. I love it because it's the least sugarcoated religion*, it's very straightforward. there's no bullshit involved like in most other religions

*many believe buddhism to not even be a religion, but more like a philosophy of how to live your life and get the most out of it without adhering to a "Greater power". the power is inside you.
