Spending time in silence is vital to your creativity and your mental health. Your conscious mind keeps very active and opinionated. If you notice the mind can be very active without taking time to slowdown and allow your soul the peace it needs.
I invite you to spend time not thinking at all. Just sit in silence and feel, hear, smell. Do not judge what is going on with your mind, just allow everything to just be and allow yourself to just experience what is. Just feel the peace and you will find that stress and anxiety will melt away.
