Whatever we cover our fear with, physically or mentally, it will never go away until we realise that all the things we fear are not real. They are psychological fears created by the projection of our mind into the fantasy that is the future. We create it all in our own heads.
The other thing is, our fears of what might happen, actually create what might happen. We manifest what our thoughts are. What we think, act and do now, creates our future.
If we stay always in this moment, fear can not exist and then we have no reason to cover ourselves physically or mentally with anything.
We can be free to enjoy being and being truly ourselves.
