There is no heaven but here, there is no next world but here, there is no hell but here. Omar Khyam. I think Morality is not about religion, it is all about combo of our conscience and common sense.

I was very fond of eastern spirituality since I was young. I felt the most valuable experiences were working with people all over the world and discussing philosophy over many years on the internet and school. When I discovered Advaita , then I was content. And it was mostly due to plain luck of my friends knowing friends and occasional discussions. I think mostly debating and discussing ideas has helped me a lot to learn my shortcomings and help others prevent it.

Growing up we were raised Catholic and I learned some valuable things from my Catholic upbringing (like humility is the no. 1 virtue, one should not wear their religion on their sleeve and the importance of 'Agape' love - this is a form of altruism). Formal education was paramount and, believe it or not the military. The military took me to other lands and cultures and taught me the warped but necessary mindset of the military. Experiences (too many - the Chinese curse comes to mind "may you live in interesting times" ) and observation were also important. Finally, my late wife taught me more than I could have imagined.

there's a good essay that I like to use to demonstrate this:
Native Thought
Versus
Christian Belief
“The foundations of each are a universe apart”
By Seen Wah Mah (Carl Knight)

 
I debated awhile as to whether to address this issue any further and have decided that I might briefly say some things about why the two ways, Native and Christian, don't fit in with each other.
 
Christianity is built upon the premise that humans are sinful, needing repentance and redemption, that they need a redeemer, and someone to intercede for them to God.  All Christian religions believe this ardently.  It is the very basis of church doctrine.
 
Before contact, the Indian looked at the world around him, saw that all things the Creator made was good.  Whether four-legged, two-legged, winged, finned, creeping and burrowing, rooted and growing, all had a relationship with each other.  Each had a purpose, there was balance upon earth and in the skies above.  He knew also he was good, as the Creator made him so.  If he did something harmful to himself, his family, his surroundings, he knew his act came from wrong thinking, and he knew he had to make the wrong right, whatever it took.  Because of this understanding of connectedness and balance, he looked at everything in terms of family.  The Great Spirit did not have a gender, and was simply considered to be the Maker Of All Things, the Great Mysterious.  He knew the Creator lived in all things, and all things lived in it, even himself.
 
Along comes the missionary who tells him he is a heathen (whatever that means), that he is sinful (whatever that was), and that he is hopelessly lost to himself and his ancestors who have walked on unless he submits himself to the teachings of the church.  He didn't know even the concept of sin. He knew nothing of which the missionary spoke, but he liked the presents he received, he liked the idea of a father.  If he did not want to give up those items which helped him to maintain his relationship with his Creator, too bad, they had to go.  If he resisted, he was heavily penalized by those he saw as stronger through sheer numbers or authority.  This created a heavy burden and great confusion within him.
 
So, many acquiesced and converted, did what they were told to do, and in time forgot their Old Ways.  The church was happy, the Indian appeared to be happy.  All was well.
 
Not quite.  The Indian experienced suppression, orders or-else, discrimination, self-hate, loss of self-esteem, etc.  If they were Christian they might fare a little better, but found themselves being made over into someone they were not.  Now generations later, descendants of these Indians look for something besides what the church offers them.  Maybe the call of the blanket is heard.  And he then tries to walk with a foot in each world.  Neither world is satisfied, and cannot be, because the foundations of each are a universe apart.  One says, even though you did nothing wrong you are still sinful because you were born in sin and shapen in iniquity, and you must do it our way.  The other says, I am good, the Creator made me so, I have love and respect for all things, if I think wrongly and do something hurtful I must correct it and make it right, I stand alone before my Maker, I am responsible for me and for all my family, I have all I need to walk a good path. 
 
Sin and guilt is the wedge that splits the two irrevocably apart.

Kung Fu tv series. I was about 10 years old, I was impressed with the philosophy and how he dealt with the various challenges, unlike my school friends who were just interested in the martial arts. It's probably why I became a pacifist

A lot of it is innate, as well as doing research. My parents gave me a great sense of values.

It was actually my love of high fantasy, born from seeing The Lord of the Rings and reading tons of fantasy fiction in my youth, that taught me the value of heroism, sacrifice, love and loyalty. It formed the foundation for my moral code that I have since built upon with more sophisticated philosophical writings.
