DEUT207 (Continued from [[DEUT213]] Deuteronomy 6:5 love TZADIK 127-9). It is well-known and apparent that love for the Holy One Blessed be He is not securely bound in a person's heart until he constantly occupies himself with it as is fitting and abandons everything else in the world besides it, as He has commanded, "With all of your heart and with all of your soul…" [this verse]. And one can love the Holy One Blessed be He only by knowing Him. The love will correspond to the knowledge. The less knowledge, the less love; the more knowledge, the more love. Therefore, one must devote himself, to the extent of his capabilities, to comprehend and to perceive, those facets of wisdom and understanding which acquaint him with his Creator. It is a mitzvah to love and to fear the exalted and awesome God, as it is written [this verse]: "And you should love Hashem your God," and (ibid. 13): "Fear Hashem your God. And this is the way to attain love of the Blessed One. When one reflects upon His acts and His great, wonderful creations, and sees through them his infinite, boundless wisdom, immediately he loves the Holy One Blessed be He and praises Him and extols Him and is filled with a great longing to know the great God, as stated by King David (Tehillim 42:3): "My soul thirsts for God, for the living God."
