Our body is like a city with many gates. Most lead to the outside world. These are our senses. Our third eye, though, is the gateway that leads within. (Upanishads)

The earth is part of your cosmic body, if we disconnect from it, we disconnect from our biological rhythms. Grounding synchronizes your biological rhythm with Mother Earth and thus the entire cosmos. (Deepak Chopra)

I have this thing. I could lie on the grass all day, a completely blank mind, simply gazing at the sun. Nothing feels more comforting than these moments spent soaking in the energy of the sun. Sure, during the day you better close your eyes to avoid UV rays bothering your eyes (and use organic sun screen), but at sunrise and sunset it is worth opening your eyes to enjoy the full benefits of the suns healing power and even to improve your eyesight.
