I know that cell phones are considered indispensable these days, but when I retired, back in the dark ages, I literally stomped my pager to death and promised myself that I would never allow an 'electronic leash' to govern my life again.
Yes, I know that cells are good for emergencies, but I lived for many years before they came into being, so I do not feel as though I must be perpetually connected to others in order to feel or be safe. And I like that there are times when no one can reach me. I have a land line, but turn the ringer off when I meditate, and at other times too. I think we have allowed our lives to be controlled by electronics. For me, the computer is enough. I need it for work, and I use it to keep in touch with overseas friends. And to study.
So, when I meditate, I meditate. Nothing electric or electronic on to get in the way. Meditation is challenging enough for me. I am so easily distracted. Having a cell phone sitting next to me would be very destructive.
