Lights, True and Engaged Buddhism

Lights in the Darkness
I'm not saying beliefs and doctrines have no value, because they do. Doctrines can be like a flickering candle that keeps you from walking in total darkness. They can be like markers on a path, showing you a way others have walked before.
Buddhists judge the value of a doctrine not by its factual accuracy but by its skillfulness. A skillful doctrine opens the heart to compassion and the mind to wisdom.
Rigidly fixed beliefs are not skillful, however. Rigidly fixed beliefs seal us off from objective reality and from other people who don't share our beliefs. They render the mind hard and closed to whatever revelations or realizations Grace might send our way.
The One True Religion I believe the world's great religions have all accumulated their share of both skillful and unskillful doctrines and practices. I also have observed that a religion that's good for one person can be all wrong for someone else. Ultimately, the One True Religion for you is the one that most completely engages your own heart and mind. It is that engagement that enables transcendence.

I left Christianity because it no longer engaged my heart and mind. Well, the heart maybe, but the mind said "Nope." But just because I walked away from Christianity doesn't mean I think Christianity or any other religion is wrong for everyone else.
Just yesterday I had a lovely conversation with the cantor of a nearby synagogue. As he spoke of being a cantor is was clear that Judaism illuminates his life and is his One True Religion. I'd have been the world's most boorish ass to even think of "converting" him.
Engaged Buddhism
It's been twenty years since I found Thich Nhat Hanh's Fourteen Precepts of Engaged Buddhism . The first one is:
"Do not be idolatrous about or bound to any doctrine, theory, or ideology, even Buddhist ones. Buddhist systems of thought are guiding means; they are not absolute truth."
I knew then that Buddhism was a religion I could enter into with my entire heart and mind without leaving my critical thinking skills at the door. And it's also why I feel no deep compulsion to convert anyone.
If you are looking for a spiritual home, I'm happy to help you learn about Buddhism. But I can't give you reasons to convert. You'll have to find those within yourself.
