Devarim 12:20

Verse 20. When the Lord shall cause good and truth in the external man to increase, as He has promised you, and you shall think within yourself, I will acquire a new will proprium that is good, because your soul longs to do what is good, as it were from yourself, you may then acquire a proprium (or feeling as if your life came from yourself) in any way that is pleasing to the natural affections.
