The human being is a composite of body and soul. Consequently, all our affairs and activities likewise contain elements of both body and soul--the material and the spiritual.
One's mundane and routine activities are generally motivated by material and physical gain. Yet the "soul" within all these mundane affairs calls out for recognition--for the infusion of these ordinary affairs with an awareness of greater objectives and a higher purpose. The giving of charity, and the support of Torah education for Jewish children--these are the spiritual incentives that ought to motivate one in his daily activities.
Each one of us is a microcosm of all Creation. The achievement of harmony between one's soul and one's material life, is the achievement of harmony between the heaven and earth.
