I am trying to ascertain the difference between these two terms, to me, they seem quite alike, its easy to separate the physical state as a clear distinction can be felt between the mental/spiritual & the physical. But how does one differentiate the mental & spiritual? Won't they always be the same? For e.g if you are depressed, is it a mental feeling or spiritual feeling? Can you be spiritually joyful & mentally morose & vice-versa?
