Although some Christians practice yoga, they do so not realising that yoga and Christianity are spiritually incompatible.
According to Drugs and Society by Hanson et al, “the word yoga is derived from the Sanskrit word for union, or yoking, meaning the process of discipline by which a person attains union with the absolute”.
Yoga is a Hindu spiritual practice which would then imply that if there is any yoking achieved by the practitioner, it would be to Hindu gods.
The bible, however, instructs us not to be yoked in such a manner (2 Corinthians 6:14-18; NIV; emphasis mine):
14 Do not be yoked together with unbelievers. For what do righteousness and wickedness have in common? Or what fellowship can light have with darkness? 15 What harmony is there between Christ and Belial? Or what does a believer have in common with an unbeliever? 16 What agreement is there between the temple of God and idols? For we are the temple of the living God. As God has said:
“I will live with them and walk among them, and I will be their God, and they will be my people.”
“Come out from them and be separate, says the Lord. Touch no unclean thing, and I will receive you.”
“I will be a Father to you, and you will be my sons and daughters, says the Lord Almighty.”
Indeed, as I had written in a previous post, Christians who practice yoga open themselves up to Kundalini spirits.
