“When he is occupied in mind and body with one of the means of earning a living, let his intent be to fulfill the commandment of the Creator, who has commanded man to engage in worldly means such as working the soil, plowing and sowing it, as it is written ‘Hashem, God, took the man and placed him in the garden of Eden, to work it and to keep it’ (Bereshis 2:15).” ~ Chovos Halevovos
