Just like in any book, be constantly aware that life is made up of various chapters. Sometimes, one chapter closes down while others may have just started. And I believe that life as it is, we must learn how to be present to the HERE and NOW moment. If not, then we might end losing plenty of those chapter's pages.
Quoting Buddha, " The secret of health for both mind and body is not to mourn for the past, worry about the future, but to live in the present wisely and earnestly." What then is striking on this quote is its invitation for us to befriend our present moment and never to worry on what has been considered as the past. We somehow divert all positive energies on the present moment.
Sadly, as reality tells us, many transactions in a day merely pass unnoticed.What usually happens is that we tend to say sorry for things in the past (we don't have control over them anymore) and on the other hand, we put enormous worry on things that are still to come.
Hence, if we only learn to appreciate life's every moment then the more that we will appreciate it. Citing one of those missed precious moment would be our meal times with family members, that instead of giving attention to our loved ones by listening to their stories and empathising with them, we stay silent while allowing our minds to wander somewhere else like worrying so much on the possible outcome of a project.
As a consequence, our loved ones will feel unloved and rejected (contrary to LOVE and ACCEPTANCE- two basic needs of man) and they will resort to something else that might not be productive or helpful to their growth. Finally, learn to be sensitive to the presence of others in your life and be aware of the NOW moment to feel that life indeed is such a precious gift.
