Such type of persons lead a balanced life, work moderately, so as to maintain current status & essential needs of life, maintain a balance of emotions, are totally detached to all dualities like life-death, good evil, happiness-unhappiness, profit-gain etc. & face them without any attachment or repulsion thinking it to be part of life. All the emotions & dualities enter into them without disturbing them like various rivers ending into Ocean without disturbing it. Such people maintain their balance & serenity in all type of situations.
Such people generally maintain a normal mental & physical health except for nutritional, environmental & other deficiencies / hazards which are beyond their control.
