Babies establish object permanence in order to feel a sense of security. Babies need that feeling of security in order to grow and function throughout the different stages of their life. A baby who does not receive a sense of security will turn into an insecure adult. Baby blankets can be used as objects that create object permeance as can Loving parental figures. A baby who has neither Loving parental figures or objects which are considered the babies, the baby does not learn object permanence and therefor becomes insecure. When we have our baby blanket long enough to develop object permeance, we no longer need to constantly reach for the blanket, since we learn it will be there when we are ready to come back to it. When a baby has a consistent Loving figure in their life they can develop object permanence.
The thing that probably surprised me the most on my spiritual journey is the realization that I was literally attempting to cling to my own body. My path is simply to let go and relax, I need do nothing. When I got for enough into the habit of relaxing, I discovered that I had this constant tension within my body and couldn't seem to figure out the source of it. I just kept practicing relaxing and I eventually realized I was trying to hold onto my body. The best way I could describe is my spirit body was trying to hold onto my physical body, which for anyone doesn't know, is impossible. I realized that I was using my body as a baby blanket. As a baby who lacked object permeance, at some point in time I started trying to use my body. When I got older, I learned that even my body could be abused and yet I still tried to hold on to it, if not even harder.
Anytime I feel tension or stress in my body I simply ask myself, "what I am trying to do" or "what am I clinging to". If I can feel that I'm trying to cling to my body, I simply let go and stop trying. Once you feel the relaxation that comes from not trying to hold the body it'll become as obvious as breathing anytime you attempt to grab on in the future. Tension comes from attempting to grab the body. Let go and see that it's impossible to hold onto. What is death? Letting go of the body, nothing more and nothing less. Simply let go of the body now and feel the freedom of eternal bliss.
The other major stressor is if I am "trying" to do something. Yoda was right on the money when he told us that there is no try. Trying is an impossibility. Repeatedly not doing something until you do it is what we call trying. Otherwise not doing something and never doing it is called failing. Likewise doing something all the time is called winning. It all still boils down to either doing something or not doing something. Try doesn't exist. So, stop trying and just do or don't do, in the end it doesn't matter for all that will be, will be. Love and Peace!
