Harner, James L. Message to the author. 20 Aug. 2002. Text message.Our mindfulness practice helps us to be more present, awake and alive for life as it unfolds. We don't practice to get better at meditating, we practice to be able to live more fully, deeply and openheartedly. Mindfulness helps us to be more aware of our inner world and how we respond to the world around us. It gives us the space and precious time to connect inward and find our inner compass so that we have a better sense of who we are, what we want and how we want to move through our days. It also gives us a skill set to be abe to slow down, to turn off our over-thinking brain so that we can simply notice and experience our life as it unfolds. Finally, through our mindfulness practice, we develop the amazing internal power of choice. When we slow down and stop our habitual patterns of behavior and reactivity, we can see that in each moment we have the power to choose how we wish to see the world and how we wish to respond to it.
Mindfulness practice is just that - a practice. And, it takes practice. As my kind and patient family will attest, it is not easy to break habits, and when we feel overwhelmed or sad or frustrated, we act out and those long-ingrained patterns of behavior which are often our default mode. When that happens, our mindfulness practice teaches us that we must treat ourselves just as we would treat others, with kindness, patience and compassion. We invite all of those feelings in and sit with them. We give ourselves permission to be human. As Jon Kabat-Zinn says, "Everything is part of the curriculum."

just likes radios and such. i had a brief discussion with my math teacher on the subject, my math teacher was an electonical engineer at Bell Laboratories for 10 years, and i asked if its possible with radio, cant it be done with any light? He said yes. what i didnt ask him was, how exactly it works, because we were in the middle of class.
so how does information travel on light waves?
bonus quesiton: what would it look like if it was sent through visible light?
It would work the exact same way as with RF waves. Radio waves are the same thing as light, so the same techniques can be used. You modulate the information in by using varations in the frequency, amplitude, and/or phase of the signal.
As Born2bwire said visible light and radio waves are two types of the same thing. Visible light is just high frequency radio waves, the same techniques could be used.
As for what it would look like, it would depend on how you encoded the information. The two common bands on a radio are AM and FM, or amplitude and frequency modulation. In visible light amplitude is brightness and frequency is color. So if you transmitted information in visible light by modulating the amplitude it would get more and less bright. If you did it by modulating the frequency it would change color.
Or, for that matter, you can "send information on light" by clicking a flashlight on and off and using Morse code!
Also see http://en.wikipedia.org/wiki/Optical_fiber" [Broken].
A traffic light is another example as are brake lights.
I stare at lightbulbs wondering if information is possibly encoded there...
so if some perseon had a radio tower that sent out visible light instead of radio light it would make everyone in the area see a tinted color of whatever color he was sending out?
and also, i knew that radio and visible light are both the light, but what i mean is, how is information sent on these waves. We cannot see radio waves and yet they carry information about sound on them. How exactly can it carry this information? what is chaging within the waves to send this information to the reciever?
Er... you do know that optical fiber transmits signal via light, don't you?
excuse me, im only in high school... so i dont know exactly what optical fiber is, i have played around with it, and know its used for transmitting internet across the world, and know its used in computers. But i don't know how exactly how it works. im asking how is information sent on light waves. but please, i am very interested in this, and would love to hear more about optical fiber also.
The answer is essentially what has already been said. Light waves, like radio waves, are just electromagnetic radiation, classified according to their frequency (or wavelength). The general idea of transmitting information is fairly simple. You have a transmitter, which takes some signal, such as a sound or an image for example, and encondes it into a specific sine wave which is transmitted through the air. Your reciever is generally tuned to look for specific frequencies, which it picks up and decodes back into the original information (sound or image, for instance). Both transmitter and reciever are typically what you see everyday as antennas.
The information is encoded in various ways, as was already mentioned. AM is amplitude modulation, where you change the amplitude (you can sort of think of this as the "volume" or "brightness" of the wave). FM is frequency modualation, where you just slightly modulate the frequency. There are other ways to do it too, such as PM or pulse modulation where you basically turn the signal on and off. When you really think about it, these modulations in the signal are no different than the simple examples of morse code or the traffic light already used. There is a kind of "key" by which you can encode and decode the signals, and this is done through various kinds of electronic circuits, the design of which is considerably more complex than could be described here
