My neighbor walked over in her pajamas at 6 a.m. to deliver a couple of empty milk cartons. I cut off the top and bottom of milk cartons and use them as a "collar" around little broccoli, kale, pepper, eggplant, and tomato plants to defend those taste treats from voles. Those critters managed to sneak under a couple of carton-collars and polish off the pepper plant inside each one.
From the outside, the milk cartons may look like a barricade (to the voles--I hope!). The plants inside have the ability to grow big and strong.
We too grow stronger in our spiritual practice when we take time to close our self off from the world--through 20 minutes of meditation, perhaps, or through going on retreat. Meditation retreats strengthen our practice so that we can taste the fruits (or vegetables) of the spiritual life.
If we allow cyberspace to sneak into our retreat or into our morning meditation, our peace of mind will be nibbled away.
Protect your practice. Protect yourself.
