Understanding Buddhism Logically

First of all, in Buddhism whatever is taught should not be taken into account, because

1). The teachings are inherited from ancestors
2). The teachings are taught by a person who you like, or you obey
3). The teachings are in books

This is how it is explained in the Kalama Sutra
"Rely not on the teacher/person, but on the teaching. Rely not on the words of the teaching, but on the spirit of the words. Rely not on theory, but on experience.Do not believe in anything simply because you have heard it. Do not believe in traditions because they have been handed down for many generations. Do not believe anything because it is spoken and rumored by many. Do not believe in anything because it is written in your religious books. Do not believe in anything merely on the authority of your teachers and elders. But after observation and analysis, when you find that anything agrees with reason and is conducive to the good and the benefit of one and all, then accept it and live up to it."

You yourself need to think logically and try to understand yourself the "core" of the teaching. There are no believers in Buddhism, what it says is believing on something may lose a persons ability of thinking and logical reasoning.
You can add missing elements, your thoughts and ideas which would contradict according to your religions.

Do you ever think any other religion or philosophy will lead you to think in a logical style like this ? Let's discuss
