He who binds to himself a joy
Does the winged life destroy;
But he who kisses the joy as it flies
Lives in Eternity's sunrise.

~ William Blake Quotes

Scientific research has shown that people who are optimistic and have an ability to accept or let go of negative memories, experiences, and events tend to be healthier and live longer than people who are pessimistic and worry about or try to change things that are out of their control. Indeed,acceptance is actually transformative, and awareness is curative. Sometimes mistaken for passivity or complacency, acceptance has a powerful magic that is actually quite dynamic and creative. Have you ever noticed, for example, how accepting your mate rather than trying to change him or her ends up improving your relationship?
The easiest way to work on letting go and letting be is to notice your tendency to want things to be different from what they are and to practice giving up that strong preference. The Third Chinese Patriarch of Zen sang, "The Way is not difficult for those who have few preferences."
There are many means to letting go, from surrendering to God's will, if that is your faith, to undertaking the mind-training techniques of Buddhism. The following are a few simple steps that aid the practice of letting go, regardless of your beliefs or religious affiliation.
Fundamentally, letting go requires just two steps:
(1) becoming aware of whatever arises within the field of your experience or consciousness, and then
(2) becoming aware of how you relate to it. These two steps can be broken down further into five steps.
We begin to realize that the purpose of meditative awareness is not to have good or bad experiences but to see how we relate to all phenomena and learn to act on them more skillfully.
# First, practice being aware of whatever arises in your experience--a physical sensation, thought, or emotion--rather than repressing, suppressing, or ignoring it.
# Second, try to observe whatever arises, without judgment or reaction.
# Third, investigate and examine the feeling, thought, or emotion, without bringing external or internal activity to bear on it.
# Fourth, if the thought, feeling, or sensation requires that you act, decide how to channel your energy into action, or
# Fifth, simply release the sensation, thought, or feeling, recognizing the transitory, empty nature of all experiences.

We see the twelve days immediately preceding Christmas as a time of great light. But really, from the moment of December through the entire month, we see as a great uplifted time on your planet and a great deal of cosmic light flows forth. That is what you are celebrating as well; that level of consciousness that can be enjoyed by each of you at this very special time and to know that it's purpose, once again, is to bring you joy, to bring you good will and to let you experience that peace that is within you, so that when December fades, the peace stays.

This is why we say, live in the moment. If you live in that moment you have a stronger chance of experiencing that peace for longer periods of time, rather than for the intercession of your ego and personality which can bring about greater negativity in the life. So, this month that comes up for you is a time to bless yourself and to bless your intimates. Moreover, it is a time to bless your planet and to let that planet survive in positivity, in brotherhood and in spiritual energy. This is a great time for all of you and a great time of goodwill to many, especially during the twelve days before Christmas.
Understand that the consciousness of The Infinite One is ever expanding and that, at times, mankind intersects with the expansion of that consciousness on a regular basis and that is what is occurring. The consciousness of The Infinite One expands, sheds more light and the entire galaxy is bathed in more, that becomes part of the One and the All, until the next phase of expansion occurs. Also, mankind is in a far more uplifted state during this time of year, so there is an acceptance of more light and more light emanates from your souls during this period of time, as well. The entire galaxy, or galactic structure of the cosmos, is filled with the radiance and essence of this light.
Consciousness is always expanding and growing, but there are times that The Infinite One sees fit to release even more light. At those times, it is experienced in all dimensions and helps to enhance all souls' growth.
The cosmic origin of the light that is flowing forth onto the earth plane during the twelve days preceding Christmas is the light of God, itself. It is the very light of God, but it is an expanded and increased light. This comes through periodic releases of light as The Infinite One determines that the galaxies are all in tune and ready to receive this light. This is a particularly propitious time on your planet because more souls are thinking of peace, goodwill and love.
