כי אף מי שהוא חכם ונבון בגדולת אין סוף ברוך הוא, הנה אם לא יקשר דעתו ויתקע מחשבתו בחוזק ובהתמדה
For even one who is wise (by utilizing his faculty of Chochmah) and understanding (by exercising his faculty of Binah) in the greatness of the blessed Ein Sof, yet, unless he applies his Daat and fixes his thought firmly and diligently on his understanding of G-d’s greatness,

He will only imagine that he fears G-d and loves Him. True fear and love are attained only by way of Daat.

This also the only true way to G-dly experiences and enlightenment. This is why we are commanded to recite the Shema Israel at least 3 times daily, and to pray three times a day, while including all of our in-between day to day activities in this energy of cleaving to Hashem. The sages say, halevai (wish you could) ve'hitpalel kol hayom (pray the whole day). The word for praying comes from the word meaning to unite and cleave (consciously, not just in deed but with feeling) ...
