Below is a very beautiful, simple quote/illustration of why people should take some time out and spend some time alone. (Photo via PresentationZen.)
For me, my solitude is my meditation. This is where I sit down and observe the ever changing nature of the body/mind phenomena. The teach from the meditation retreat (S.N. Goenka), addressed the UN in 2000 about how meditation is “the tool, for all religions to end global suffering and enable world peace”. (Zencast)
This is once again, another example, of how the east and the west have the same meaning/root message, just different terms.
