What is the divine perspective of the saying: “The hand will not reach for what the heart does not long for?”

This is a truism that "humans are love-based beings, and what serves the heart serves the human." There are many ways this is expressed because love is such a huge factor in everything of importance to human existence. All that is an accomplishment, is about the giving and experiencing and the receiving of love to one degree or another in some flavor. Love has many colors and many flavors. Anything that enriches is a working of love. Anything that helps one grow, helps one learn, helps one meet a goal or accomplish something is an expression of love in some fashion. All of human interrelationships are governed in terms of their quality and effectiveness by the amount and quality of love involved as opposed to its absence or denial. The highest attainment in life is to live with a vibration of loving kindness in all one thinks and does. Any human endeavor can be done in a loving way, and to the extent love is withheld, there will be a diminishment.
