Last month, I visited to the TOA PAYOH Monastery. I brought a small book, the name called "JUST BE GOOD". There're some explanations about BUDDHISM and meditation practices. This link is mentioned in it.
Please let me share you some valuable words from this small book...
"The idea is not to dwell in the pass, or dream of the future. Observe and live each present moment as it comes about. You will then be truly living and able to see life as it really is. "
