Arcana Coelestia # 5668
5668. 'And gave them water' means a general influx of truth from the internal. This is clear from the meaning of 'water' as truth, 2702, 3058, 3414, 4976, in this case truth in general. This is why 'giving water' means a general influx of truth; and the reason it comes from the internal is that this took place in Joseph's house, 5667. A general influx of truth is enlightenment that makes it possible for truth to be discerned and understood. This enlightenment is provided by the light of heaven which flows from the Lord, a light which is nothing else than Divine Truth, 2776, 3138, 3167, 3195, 3222, 3339, 3485, 3636, 3643, 3993, 4302, 4413, 4415, 5400.
Arcana Coelestia # 3643
3643. I have noticed that those in heaven dwell beneath a clear, bright sky like that of morning and midday, extending also towards evening, and likewise in a warmth like that of spring, summer, and autumn. But those in hell dwell under a dim, cloudy, and darkened sky, and also in the cold [of winter]. I have noticed that between the two in general a balance is kept; also that insofar as love, charity, and consequently faith are present in angels, they dwell under a clear sky and in the warmth of spring, and that insofar as hatred and consequently falsity are present in those in hell they dwell in thick darkness and in coldness. And as stated above, the light in the next life holds intelligence within it, the warmth love within it, while thick darkness holds insanity within it, and cold hatred within it.
