I grew up a Christian, but have recently discovered Siddha Yoga as a great spiritual tool,is God ok with this?

I have always worshipped Christ while in Catholic school up until the age of 15 when i changed to a public school and stopped going to church, recieving communion, ect. I am now 29 years old and know I need to integrate a strong spiritual side into my life including getting closer to God. I have been attending some Siddha Yoga meetings and have found that the relaxation and feelings of inner peace is very similar to that of church. Now that my wife and I have a baby I am going to have him baptized in a few months and intend on going to a Catholic church every weekend and refreshing my relationship with God. The basic idea behind Siddha Yoga is that God is everywhere and in everything and dwells in each of us. This can be experienced by calming the mind and controlling breathing among other things. I feel it is essentially not a religion, but rather a way to fine tune my connection with god and the universe. Will I be condemned by Christ/God if I embrace both entities? God Bless!
