During cyclones and storms all turbulence is on the surface of the ocean. A diver knows, a few feet under the fearful surface is a calm and tranquil ocean. The deeper you go, the quieter it is. 

All your fears and worries are on the surface mind. Deep in the recess, you have a tranquil space waiting for you. There, no virus, no disease or fear of untimely death can reach. You belong to that kingdom of Peace and Joy. 
As you go deep inside you, you rise higher and higher till you find the peak of enlightened Self.
