While living and working in the desert my skin would get dry. I didn’t think about much other than I purchased jugs of skin lotion and applied the lotion all over my body, every night after a shower.
Somewhere along the line I heard an expert say that dry dead skin is constantly falling off our bodies. The dead skin, however can cling to the body and make it difficult for the skin lotion to be absorbed.
I looked at my skin and found flaky dead skin all over. The dry skin was an impediment. Basically, it blocked the lotion I applied from reaching the skin. I scrubbed harder in the shower to get rid of dead skin. I also applied less and less lotion until I got to the point of rarely needing it.
I think back on this experience from a metaphysical view and can glimpse how thoughts of fear, envy, and anger are dead thoughts. Negative thoughts do me no good. And if I let negativity cling to my mind, they can even stop me from absorbing good (moisturizing) thoughts that come my way.
