....... A Guide to Spiritual Enlightenment ....... By Eckhart Tolle, was published in 1999. Tolle helps us to be conscious of NOW. He relates on page 43: "Since ancient times, spiritual masters of all traditions have pointed to the Now as the key to the spiritual dimension. Despite this, it seems to have remained a secret. It is certainly not taught in churches and temples." One could add, "nor in the Kingdom Hall, where the faithful are urged to be ' time conscious.' " (Turn in your time, It's convention time again, Don't waste time on worldly pursuits, The end is very near, The very near future, Soon....) Tolle says that identifying our whole being with clock time, past time, future time, rather than just using these as conveniences or for reference or as necessary evils, is part of the greatest obstacle to personal enlightenment. He says much, much more than this also. You'll probably have difficulty putting the book down. He even uses a special symbol at convenient points where he recommends meditating on what you've read, so that you can go toward a permanent shift in consciousness rather than just use the material for intellectual purposes.
I would like to recommend it highly to all posters here. It's available thru Amazon at a lower-than-publisher price.
