10605. 'And be ready by the morning; and you shall come up to Mount Sinai' means a new beginning in the revelation of Divine Truth. This is clear from the meaning of 'the morning' as a rising state or a beginning, here a new beginning, dealt with below; and from the meaning of 'Mount Sinai' as heaven, from which Divine Truth flows, and so revelation comes, dealt with in 8805, 8931, 9420. The reason why 'the morning' means a rising state or a beginning is that states are meant by all times and seasons, because in heaven they have no thought of any time or season, only of the changes of state that affections and consequent thoughts undergo, and changes of state there are like the times of day, which are morning, midday, evening, and night, the morning being that from which they begin. It may come as a surprise to everyone that in heaven there are no times or seasons, when yet those there live among one another as people do in the world, though they are different from them so far as intelligence, wisdom, and blessedness are concerned. But the reason is that the light there radiating from the sun, which is the Lord, does not undergo daily changes like the light from the sun in the world. Instead it varies in accordance with the states of love and faith among the angels, who undergo changes of state like the states of heat, light, and shade every day on earth. Why this should be so is that the light there from the Sun, which is the Lord, is Divine Truth, and the heat from that Sun is love. Angels are affected by these just as people are in the world by the conditions of light and heat.
The light in heaven comes from the Lord as the Sun there, see in the places referred to in 9548, 9684. That light is Divine Truth, which is the source of the intelligence and wisdom that angels and men possess, in the places referred to in 9548, 9684, 9571(end), 10569. Times and seasons there are states, in the places referred to in 10133. In heaven states are varied like the times of day and seasons of the year in the world, 5962, 8426. Morning comes at the beginning of those states, and so is a new beginning, 8427, 10114. In heaven there is the state of evening and twilight, but no state of night, 6110.
