Excerpt from Eckhart Tolle's 'Power of Now' :
Your 'life situation' exists in time. Your life is now. Your 'life situation' is mind-stuff. Your life is real.
Find the "narrow gate that leads to life". It is called the Now. Narrow your life down to this moment. Your life situation may be full of problems - most are - but find out if you have any problems at this moment. Not tomorrow or in ten minutes, but now. Do you have a problem now?
When you are full of problems, there is no room for anything new to enter, no room for a solution. So, whenever you can, make some room, create some space, so that you find the life underneath your life situation.
Use your senses fully. Be where you are. Look around. Just look, don't interpret. See the light, shapes, colours, textures. Be aware of the silent presence of each thing. Be aware of the space that allows everything to be. Listen to the sounds; don't judge them. Listen to the silence underneath the sounds. Touch something - anything - and feel and acknowledge it's Being.
Observe the rhythm of your breathing; feel the air flowing in and out, feel the life energy inside your body. Allow everything to be, within and without. Allow the "isness" of all things. Move deeply into the Now.
You are leaving behind the deadening world of mental abstraction, of time. You are getting out of the insane mind that is draining you of your life energy, just as [the collective mind] is slowly poisoning and destroying the Earth. You are awakening out of the dream of time and into the present.
