Our state of mind plays a major role in our day-to-day experiences as well as our physical and mental well-being. If a person has a calm and stable mind, this influences his or her attitude and behavior in relation to others. In other words, if someone remains in a peaceful and tranquil state of mind, external surroundings can cause them only a limited disturbance.
Each of us is here for a brief sojourn; for what purpose
he knows not, though he sometimes thinks he senses it.
But without deeper reflection one knows from daily life
that one exists for other people.
No man is an island, entire of itself; every man is a piece of the continent, a part of the main. If a clod be washed away by the sea, Europe is the less, as well as if a promontory were, as well as if a manor of thy friend's or of thine own were: any man's death diminishes me, because I am involved in mankind, and therefore never send to know for whom the bells tolls; it tolls for thee.
