I’ve done comparable religious study on my own, over the years.
I’ve learned about Taoism, Buddhism, some Hinduism, and Islam.
The first three have some similarities in Catholicism, but merely on the mechanics on the surface. Deeper into them, they are much different.
Islam, believing in one God, the God of Abraham, is where our similarities end.
For many, especially young people, Buddhism, looks like you can have religion, which doesn’t demand much of you. It has the peacefulness, without all the rigid doctrine and such.
This is only true so far as you want to grow spiritually. If you desire to grow, you must then learn the 8-fold path to enlightenment, and of course follow a life of discipline.
Many have found that Catholicism isn’t so difficult after all.
Also, many people will take the parts they like in these eastern religions, and throw out what they don’t like. This is what the New Age movement did, essentially bastardizing down, not only Eastern religions, but Catholicism as well.
So, go ahead and learn about Buddhism. I would learn it under the guidance of a Catholic priest, which there are teachers out there, including Father Merton, but his no longer with us.
Also, a good book that I read, “Jesus Among Other God’s,” by Ravi Zacharias, who is a professor of comparative religious studies, gives a good reason why we follow Jesus.
He is originally from India, and raised in Hindu tradition, although his parents were not really devote Hindu’s. Nonetheless, he knows Hinduism, Buddhism and Taoism, inside out. He shows you how they compare to belief in Christ.
