What is spirituality without Christ?

 It is basically a vehicle without an engine. 

"But I am feeling good"

You are trying so hard, though. You can be spiritual without Christ. To be precise, you can feel good without Christ. There is no problem in that. God is not a tyrant. That is why he has given you free will.

But if you want the real material. Solid. 100% no bs thing. Then you go to Christ.

Everything works so smooth. Perfectly fine. 

See, now you are not meditating or anything. You are a perfectly tuned working machine now.
