If we keep thinking about practical negative possibilities of ever increasing number of Covid19, we will sink more and more into stress and anxieties. We will successfully damage our health. The more our mind is gripped in stress, the more damage to our immune system, naturally, the more susceptibility to positive corona!  Stop. Pause, calm down, get more often inner rest through meditation, and allow natural healing to your body-mind. Isn’t it your charity to the world that you decided to add positive vibrations of health and healing, and not negative vibrations of death and despair? 
It is your choice!
