Buddhism
Watched the life of Siddhartha Gautama last night and his quest for meaning. I pretty much figured out what he was looking for before the story came to when he found his answer.
I have not studied Buddhism before or even knew who  Siddhartha Gautama was.

They describe Buddhism as a religion in many articles I have just searched. I really do not consider it a religion. I consider it just passing on lifes meaning to the next generation.

I find this article to be of interest.

What is the purpose of life?

excerpt:
Religion teaches a person how to calm down the senses and make the heart and mind peaceful. The secret of calming down the senses is to eliminate desire which is the root of our disturbances. It is very important for us to have contentment. The more people crave for their property, the more they have to suffer. Property does not give happiness to man. Most of the rich people in the world today are suffering from numerous physical and mental problems. With all the money they have, they cannot buy a solution to their problems. Yet, the poorest men who have learnt to have contentment may enjoy their lives far more than the richest people do. As one rhyme goes:

    'Some have too much and yet do crave
    I have little and seek no more;
    They are but poor though much more they have
    And I am rich with little store.
    They poor, I rich, they beg, I give;
    They lack, I have; they pine, I live.'
