What does life is a barren field frozen with snow means?

This statement seem to have a philosophical side,so let me just try-life is certainty equipped with joys and sorrows,what you feel one time,you feel the other next moment,so you see nothing is permanent,yet we all want happiness for ourselves ignoring the above which you may call a fact of life.and when we cant seem to get joy everytime we want - we get depressed.so meaningless attachment to one aspect ie happiness and its expections is nothing but simply a non prolific idea.

May this helped you a bit if not all in the right direction.

Best wishes

staying unaffected by both happiness or sorrow or taking both as the same is what i want to recommend to all,never flow either side. Else one would be dissappointed.
