I don't know how you would describe, a full-blown religion, Dennis. I used to be an HIV/AIDS activist and we knew there was no such thing as
full-blown AIDS. You either had HIV infection or AIDS, which meant you were seriously ill.
Likewise, the yoga starts off innocuous enough, standing on one leg, which my little one finds funny.
Eventually in the higher grades, they move onto teaching the fundamentals of yoga, chanting OM etc, which has caused other believers to pull their kids out of the program altogether.
Here is my testimony, for what its worth.
More than a decade ago, while I was working outside the home, my shoulder muscles would get taut as soon as I started working on the computer, which would take about 20 mins to relax. I realised that I needed to strengthen my back muscles, so I began to do some back exercises. This one in particular involved lying on my stomach and raising my torso causing my back to arch and it brought tremendous relief. I was at the time seriously considering signing up for yoga classes. Soon after my conversion though, I came across a coffee table book on yoga and I saw that the posture I described above was used in yoga to worship the snake god (a position similar to a cobra rearing its head). Other postures included worship of the sun god ( surya namaskar - meaning bowing to the sun ) and many other of hinduism's billion gods . I promptly stopped doing the exercise and believe me, I've
never had those muscle tautness since.
2 Thessalonians 1:11 Wherefore also we pray always for you, that our God would count you worthy of this calling, and fulfil all the good pleasure of his goodness, and the work of faith with power:
Now, post BT, I believe that God was confirming to me, at the time, not that the exercise per se was wrong, but that yoga and all that it involves does not bring glory to God. All that I've found out in my research about yoga in subsequent years as a Christian, has confirmed this to me.
