Having an unfortunately long past history with hinduism, yoga, new age, buddhism, etc., I would like to add my :twocents:
While the physical stretching exercises of yoga superficially appear benign, the entire system is based on a philosophy which is not compatible with Christianity. If one studies yoga more deeply, one encounters consistant expressions of various hindu deities, who are claimed to have juristiction over various energies and nerves, etc. These hindu deities are not our God.
I believe it’s impossible to separate what we in the “west” think of as “yoga” from it’s roots - which are deeply embeded in the hindu religion.
In my experience I’ve encountered not one American Yoga studio that did not - at some point - introduce mantras, hindu deity concepts and such to their students.
Also, as stated above, Metta is a buddhist concept - which translates fairly well as “loving kindness.” Because buddhism is, essentially, atheistic - the person is reliant on their own actions, for their “spiritual” growth and ultimate “soul-liberation.” (Not exact, but that’s the best I can put it so it makes sense.)
In buddhism there is no reliance on God. Actually, in buddhism, essentially, there is no God. There is no Salvation Economy. There is no Heaven, Savior, or Community of Saints. Oh, and there is no Holy Spirit. So buddhism’s tenents of faith (so to speak) are based on a philosophy that is is in direct conflict with Christianity.
We Christians rely on God’s grace and mercy. We rely on Jesus’ teachings and demonstrations of compassion. We do not need to add Metta prayer-mediations to our Faith.
Our faith is whole and complete as it is - especially as it is held within the doctrines and sacraments of the Roman Catholic Church.
So the Metta prayer-meditations should be stopped immediately as well.
Frankly, I it’s my experience-based opinion that because of the basic belief systems of hinduism and buddhism, toying with any of this stuff - for any reason, even with the best of intentions - is fraught with peril.
