Which one of the five rules in OP are rotten fruits?
rcscwc, I practiced yoga, as an atheist. I studied the yoga sutras of Patanjali. I stopped practicing when I came to the realization, that to continue in my study and practice, I would have to believe things I did not believe, as an atheist.
As a Christian convert, the “problem” I see with the sutras of Pantanjali, is that the divine is found within. This is not a Christian ideal. The divine is found in a Person, Jesus Christ. He is not within. He is external to ourselves and He is Who we follow.
I cannot follow two masters. I cannot follow Jesus and Patanjali at the same time.
You focus on the limbs of yoga, which is what attracted me to the philosophies of yoga. But the philosophies do not end there. As you say, they lead you to a true yoga practice, which in my opinion, is not a Christian practice. Some of what I have read here, is truly syncretic, not surface similarities.
My opinion is, to practice both yoga, in its true form, as taught by Patanjali and Christianity at the same time, you either have to become syncretic or you have to keep a very clear wall between the two practices.
Syncreticsm is a heresy. And a wall between beliefs and practice, is outside the beliefs of yoga. Your mind cannot be un-yoked from beliefs, if it is, you have to find ways to yoke them, at which point, you will become syncretic.
There is no possible way to truly follow these two masters at once.
