What is the spiritual meaning of renewal?

The second day finds the spirit awakened from repose so absolute that it can only be expressed by the word renewal. 

We are renewed in every sense by our seasons of withdrawal, partly because we are so passive that the influx of our surroundings takes full possession of us.

Perhaps it is well to say that what is called day and night is but the nearest expression to the reality. 

In the morning, there is a brighter place in the east. It is like a rosy dawning, very clear, and grows brighter for a time until it is like sunlight, but brighter and yet softer. This brilliant spot rises about one-third of the way to the zenith and remains there until the day declines, and then slowly descends to the horizon and fades away. Does not disappear as the sun does, but becomes more and more delicate until it merges into a lovely dusky gray, very nice to rest in. 

Like a beautiful twilight.

Sometimes, there are such waves of colour breaking over the sky that it is a perfect wonder to see. 

Like ten thousand rainbows following each other, but broken into masses of glory.

They tell me that some of the archangelic spirits are near there and their sphere is one of colour. They are passing by and we see their glory as of those who  dwell in the innermost courts of the Almighty.
