Nathan of Breslov,
Sichot Haran
“ Most people hardly ever think of God. The Bible therefore reminds us, 'Know that the Lord is God! Know the God of your father! Take this into your heart and mind until it is tightly bound up there every instant.' It is therefore written, 'Know this day and consider it in your heart that the Lord is God.' The main perfection of knowledge is binding your mind to your heart. You then know 'in your heart that the Lord is God.' When this enters your heart, you will certainly gain a deep awe of God and not sin. ”
