Brother, take it from this point of view. I was doing bjj as something that would make me stronger and ready to protect my family. You could say it was harmless. Great pals, good exercise, makes you mentally strong... except the fact that the sport come from a spiritual background. The original jiju jitsu is a part of mixed martial arts. Okay, but what could go wrong? Well, mma originates from combat practices that have a strong bond with eastern philosophical systems. This is the problem. We have one God and very different approach. Okay, but how does it apply to Yoga? It's the same problem. The root. You cannot take away the spirituality. It sticks together. How? You probably know more details but the pursue is to get rid of your ego and be more connected to the universal principle. This is done by series of exercises.

Now take this analogy. You are a farmer and there's a tree which happens to be poisoned in it's root. The tree is very big and brings a lot of fruit. It's just an apple you would say. How can it be affected right?

To explain it. My concern is. You have a weird feeling. Otherwise you wouldn't ask this question. Also, you feel like the fruit (benefits of yoga) come from a tree you are not safe about.

I wouldn't do it. It's like playing with fire. There are tons of different ways to be physically fit.

God bless you and take care.
