Time is infinite, yet feels so scarce.
I have been struggling with time management as I believe most people do to some extent in our society.

A dear friend who studies the Course in Miracles sent me some beautiful quotes about time from the course:
"The only aspect of time that is eternal is now."
"Now is the closest approximation of eternity that this world offers. It is in the reality of "now," without past or future, that the beginning of the appreciation of eternity lies."
"Now is the release from time"

There are many resources to discover the value of time in the now. I have read and found useful, "The Power of Now" by Eckhart Tolle and "Where Ever You Go, There You Are", by Jon Kabat-Zinn. I am sure there are many others. Please share with us those which you find most valuable to you.

It is interesting how many spiritual traditions have insight into the value of being present or mindful. One of the clearest traditions that teaches and values being present is Zen Buddism.
There are opportunities to learn and experience mindfulness meditation in most local areas. As frequently as I am able I join the meditation group at Insight Meditation Center in Redwood City, CA.
