Russ,
I am glad you have commented. My first question to you would be, "What has your Jesus Christ saved you from?"
Yoga is to "yoke" the body, mind and spirit together. Why would you want to connect your spirit with your flesh that you know is going to die? Your body will die one day right? Where will your soul go then?
You said that historically people experience kundalini "distress, depression, academic force of will." Your response after it happened was fear, so you went to a guru. I believe that seeking after God starts with fear (of Him) and though He is terrifying to us (because we are so insignificant in comparison), we are left having been fixed. Joy and salvation from the consequence of eternal death are the fruit of Jesus Christ. Which would you choose? Joy or depression?
It is scary to think that Satan must know the Bible better than any of us. That is why he is so good at switching our definitions. He does take Biblical illustrations (like fire at penticost), and would have you believe that his side is right. Hindu tradition and the Bible both have "the snake" in it. But please understand what the snake is! The snake tricked man into thinking he could become like God. We are not gods.
We must measure ourselves against the Bible and do more than just hear Biblical terms. If we do not commit our hearts completely to this we will be deceived. (I am talking to all believers).
Reiki is dangerous too. 1 Timothy 5:22 says "Do not be hasty in the laying on of hands, nor take part in the sins of others; keep yourself pure." Reiki is correct in saying that there is "energy" transfer in physical contact, but that does not mean we can assume it is a good thing. The pinnacle of human physical contact is sexual intimacy, and do you think that it would be a good thing to share with anyone at any time who simply wanted it? No! There is only one context that it is correct. We must measure the source, test the spirit against the Bible.
The Bible is a book that none of us will completely understand and that is okay, we're not meant to, it is not in our ability to. However, there is an underlining message that is consistent throughout the whole book and it is Good News! Do you understand what the Good News is?
I hope that we are not seeking each other's opinions but instead God's. I would challenge you to not just defend your faith in Christ but to be sure you know who He is.
From one filthy, rotten leper to another. I am deeply thankful that Christ can make us clean!
God bless you,
Nathan
