I Lived In a Zen Center For a Few Years
There are many forms of Buddhism. They differ considerably. Some are more like a religion. Others are more of a practice. I lived in a Zen Center for a few years. I can tell you about that.
All belief systems are interpreted through the eyes of the individual practitioner. To me, buddhism basically explained that 'Life is suffering', which made sense at the time.
I think most people seek new ideas and belief systems because they have big questions and some degree of suffering.
Buddhism also teaches that this suffering is caused by our thinking and that the Buddha found a solution to this suffering and so can anyone else.
The Zen style has people work towards finding their own answers through meditation practice and other practices. I think it is a lovely practice. It basically gives you the time, opportunity, prompts and help to understand some of the ways the mind works so as to not get tripped up by thinking.
If more people meditated regularly, the world would be a place with more mediatators!!!!
