And regarding your questions about what Rabbi Moses Maimonides, may his memory be blessed, wrote: 'One should direct their heart towards the Shekhinah and pray,' and in the Guide for the Perplexed, he wrote that the Shekhinah is a created light, and so on. By your question, it is revealed that you consider yourself wise in your own eyes but have not learned ethics. And is it the proper way for the questioner to question their questioner?
Nevertheless, I will not hide my words from you, even though you acted unfairly! I will state that it is straightforward and known to every intelligent person well-versed in the books of Israel that the term Shekhinah is used in three instances: referring to God, as our Rabbi wrote in Hilchot Teshuvah, Chapter 7: 'Teshuvah is great, as it brings a person close to the Shekhinah,' as it is stated, 'Return, O Israel, to the Lord your God,' and it is said, 'And you did not return to Me, says the Lord,' and it is said, 'If Israel returns to Me.'
Meaning, if you return through repentance, you cleave to Me, and so on. Additionally, it refers to the virtue of repentance, as it says, 'Last night, this person was separated from the Lord God of Israel,' and today, they are attached to the Shekhinah, as it is stated, 'And you who cling to the Lord your God,' crying out and immediately answered, as it is said, 'Before they call, I will answer.' The same idea applies to his words in Hilchot Tefillah, that if one is in a place where they cannot direct their thoughts, and so on.
Our ancient sages also quoted this, and here and there, the verse is employed, and may my tongue cleave to my palate if I do not expound on the greatness of the divine presence, which is united with me.
