However all of the above was specifically when the Jewish people are on a very high level and the Shechina dwelled in Beis Hamikdosh.
Then the Jewish people received their life force only through the Godly soul, from the inner Essence of God through the name Havayeh.
However when the Jews fell from their high level and through their sins caused “The secret of the exile of the Shechina,” -as it says “Because of your sins the Shechina went into exile.”
In other words, the descent of the lower Hei into exile causes the energy to go to the supernal ministers – that govern the countries of the gentiles, and give the life force to the animals or vegetation there.
As such, just as any animal in that country can receive life-force, so too can the body of the Jew who sins.
In actual fact, a Jew who sins in thought, speech and action actually receives a greater energy from the other side – for the reason that whatever a person is thinking, saying or doing – if it is good, the energy comes from God; but if, as a person has free choice, they choose to think, say and do bad, then their energy comes from the dark side – and the dark side can only have energy from the bad that people do (and as they have given it energy, they receive first from it.)
This occurs specifically in exile – and this is the secret of the exile of the Shechina.
That it has to so to say, give to the dark side, that God despises.
However when a person does a proper Teshuva than they remove the energy that they have given to them.
For when a person does Teshuva – they return the energy of the Shechina to her proper location.
And this is the return of the lower Hei from her exile – like it says, “And God will return her captives” in other words “With your captives” that God will return together with the Shechina.
