With the comparison part of the two is that they both try to help you relax and have better control of your emotions. The contrast between them is the subtle mind deals with you breathing which you can take with you anywhere and with the loving kindness which deals with listening to something that helps you relax. With the subtle mind I use this on a daily basis to help me relax and stay more calm. I really don't like the love-kindness routine with listening to things to help me relax. Spiritual wellness I believe connects all three mind, body, and spirit. With your spiritual wellness in tact you will be able to have better understanding of things around you and being able to control things around you also. With spiritual wellness your mind and body becomes more healthy and stable. It has helped stay calmer and less angry in my daily life. My spiritual wellness has made me more in tuned with myself from a clear mind standpoint.
