Human beings descended from the unity of unindividualised spirit into the duality of matter where they are able to develop their individual selves. The time of pre-history was the time of the descent. History begins when human individuality has started to have a significant impact on consciousness. When the descent has reached its furthest point, meaning consciousness is fully embedded in matter, it must be redirected upwards or else it will stay where it is, stuck. Its momentum has carried it down to the earth but now something radically different is required to turn it around and start it on its ascent back to spirit. That something was the birth of Christ.
We had come down from the realms of light into material darkness. We had reached the bottom. Christ was born to reorient us to the light and enable us to transform our earthly selves into true (rather than potential) sons and daughters of God through assimilation into his being. This requires that we freely give ourselves to Christ and so, in return, can partake of his being. Unity of consciousness is known in a way that combines the individual with God without loss of either. Originally, we were one with God but did not know it. Then we knew we were separate from God. The intended final state is that we become consciously one with God and with all other spiritual beings in a union of love and creative self-expression.
Christmas is at the darkest time of the year, when the days are short and the nights are long. The symbolism here is that the first Christmas occurred when human consciousness was at its darkest, at the nadir of its descent, deeply locked into the world of matter. Christ's birth changed that even though it may be hard to believe, given what has happened since and especially given the rampant materialism of the present day. But Christ's birth served to turn us around and re-polarise our individual selves to God. If we accepted him, that is. Many people have done precisely that but we live at a time of mass apostasy when recalcitrant souls are being given another, maybe a last, chance to turn to the light. The options of God or no God are being clearly laid out but the choice is not made easy or it would not be a true test of the heart. Evil can appear good to those whose heart inclines towards evil. This is a time of reckoning.
The symbolism of Christmas is that of light appearing in darkness. Let us remind ourselves of that at this time of deep outer darkness. Christ was physically born 2,000 odd years ago but he can be born in us spiritually at any time. Light in darkness.
