It is a great idea to learn to quiet yourself so you can pray and hear and feel the presense of the Lord, Fabian. This is a very common exercise people use to clam down the comotion so they can pray. Learning to observe habitual and unwanted reactions and thoughts that are not true and giving them over to Jesus to take away from you is a great healing method for many people.
The relaxation exercise does not call upon Jesus to be with you before beginning, so always do that. Talk with Jesus at the end, too.
Thanks for sharing your experience. God bless you. :)
Thank you! and I do say thanks to God after my silent prayer.
