Kaisipang Hudyo sa Mga Awit 84:3: Duties

One can also explain the intent of "And you shall love the L-ord your G-d with all your heart, and with all your soul, and with all your might" (Devarim 6:5) to be referring to cleaving to the love of G-d inwardly, and to exhibit it outwardly, until the genuineness of the believer's love will be recognizable inwardly and outwardly, privately and publicly, in a way that it will be manifested uniformly and in the proper way, in the same amount and in the same level, as David said: "my heart and my flesh cry out for the living G-d" (Tehilim 84:3).

Then, when the believer engages in them with his heart and mind, and exerts himself to the best of his ability, G-d will open for him the gates of spiritual qualities, and he will attain with them what is beyond his ability, and he will serve G-d with his body and soul, with his outer and inner being, as David said: "my heart and my flesh cry out for the living G-d" (Tehilim 84:3).

One of the pious would say: "do not praise empty praises, meaning, empty of having your heart in it, rather, it should be with your heart in it, as David said: "With my whole heart have I sought You" (Tehilim 119:10), and "I entreated You with all my heart" (Tehilim 119:58), and "my heart and my flesh cry out for the living G-d" (Tehilim 84:3).
