אַשְׁרֵ֣י אָ֭דָם עֽוֹז־ל֥וֹ בָ֑ךְ מְ֝סִלּ֗וֹת בִּלְבָבָֽם׃
Happy is the man whose strength is in Thee; in whose heart are the highways.
Mesilat Yesharim
That which will help greatly in acquiring Chasidut is great observation and much contemplation. For when a person contemplates much on G-d's great exaltedness, blessed be He, and His absolute perfection, and the immeasurably great distance between His greatness and our lowliness, he will be filled with fear and trembling before Him.
