Down" is used many different ways, and its spiritual meaning in the Bible is highly dependent on context. Phrases like "bowing down," "lying down" and "falling down" are defined primarily by "bowing," "lying" and "falling"; there is also a great difference between a person descending, the Lord sending fire from heaven and someone handling an object, to offer a few examples. In a very general sense, though, "down" indicates a lowering from more internal spiritual states to more external ones. That's why the journey is described as going "down" to Egypt from Canaan, and people from all quarters go "up" to Jerusalem. It's also why the Lord comes "down" to us, which generally indicates a state of judgment.

2271. That 'he spoke to Him yet again' means thought is clear from the meaning in the internal sense of 'speaking'. Speaking or speech is nothing else than that which flows from thought; and because things that are internal are meant by those that are external - such as understanding by 'seeing', the understanding by 'the eye', obedience by 'the ear', and so on - so thinking is meant by 'speaking'.
