Play with Yoga all you want. Learn all the knowledge of the secrets of the universe that you can find. But in you learning, remember to rely on the things of the Bible, or you will lose everything.
Mate, I have a question for you... Did you read and analyze the whole Bible?
Because, if you did it I am sure that you will not wrote this things about Yoga. Everything that is mentioned in the Yoga you can find in the Bible. In the New Testament, when Christ rose from the dead he send the apostles in the different area of the world to spread The Holy Scripture. Do you know which apostle was send in India?
How many chakras are in the body? How many commandments there are? How many apostles are? The answer of the three question is 12! Everything that is is mention in the Bible is always connected with the number 12! Do you think that there isn't some logic here?
I am sure that any person who will first read about the Yoga and then start to read the Bible (New Testament) will understand the acts of the apostles.
Again, the Bible is NOT basically meant to be a history book. Nor is meant to be a book of things like Yoga.
Simply because the Bible has laws it, doesn't mean that some of these laws cannot be found in places like Yoga. Good laws and understandings are found all over the world, in all kinds of writings, and in all kinds of societies.
The point of the Bible is that God made all the laws, and set them in peoples' hearts, and then re-gave the best of them through Moses because people were forgetting them. The whole idea behind doing this was to prepare the setting for the Savior, Jesus Christ.
In other words, the laws for living can be found in many places. But the law for eternal life can only be found from one source, the Bible. You, yourself, said above that Jesus sent apostles to India. Why not honor the Bible, the only source that tells about Jesus Christ, the only salvation, even though there have been many books written about Him.
Yoga and its writings have been around a long time. Yoga existed long before Jesus came... even before the time of Moses. Yet it never had any exact information about Jesus. The best it had was some symbolism about how there might come a time of salvation. If there are writings in Yoga that have incorporated Jesus into Yoga, written at a time following the time of Jesus, great. Now, get into the Bible and find the details.
Laws and wisdom of earth and science - like how many Chakras are in the body - don't have anything to do with salvation. They exist with or without salvation. Jesus is the only way of salvation. In fact, one of the old meanings of the word, "Nicolaitans," in the Revelation is, the people who combine Christianity with Eastern religions. People who practice Yoga regularly, have essentially turned it into an eastern religion.
Keep Yoga separate from Christianity, because it IS separate from Christianity. Yoga teaches good living in this life. Christianity teach the only way to everlasting life, through Jesus.
