What is "grace of state"?

In the context of vocations, what is a "grace of state"? not to be confused with "state of grace " (having sanctifying grace ) Chad Ripperger, *Introduction to the Science of Mental Health* , Chapter 26: Misdiagnosis of Supernatural Activities: >These inclinations also find themselves in what are called “graces of state.” For example, a priest who has received the sacrament of Holy Orders also receives certain graces which incline him toward the fulfillment of his office as priest, i.e. to offer Mass, hear confessions, etc. When the priest fails to fulfill the obligations of his state, he will often enter into a kind of depression or state of sorrow or unhappiness. This is the result of the lack of fulfillment of the desire of the inclinations of the graces of state. Are "graces of state" different from sacramental graces from Holy Orders for priests or from Matrimony for marrieds? Is "grace of state" a type of sacramental grace? Or can those without these sacraments also receive "graces of state" (e.g., to help one live the single life or lay religious life)?
