Another twisting of Scripture to prove a weak point. Twisting Jesus' words could be seen as blaspheming Him. As we can see through Jesus' experience with Satan in the wilderness, how Satan quotes Scripture out of context.The Bible never says to pray wearing trousers or polyester. Is it forbidden to do so?
I already gave an example, that the Bible commands rejoicing, which involves the emotions. Regarding visualization,
Matthew 23:37 says,
Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind.
