How can there be so many differences between schools of Buddhism? How can we tell which one is the most accurate to avoid having a wrong view?

Thank you, I think those are

Thank you, I think those are great questions--probably with long and various replies. That inquiry must also have been on the background of the doctrinal debates and development flourished during the Abhidharma period. The first one especially is very much related to the subject of our course--and so is the second one,-- and everyone is welcome to share your thoughts, with references. If you're interested, you should develop your own response as a topic for your essay.
