A question that can be rather puzzling is the following: if we are all human beings having an experience here on Earth, how come that our experiences are so different - provided that the destination is the same?
Looking around, you keep seeing extremes: one life that is full of good feelings, people who encounter many opportunities to love and be loved (independently from the final outcome) while others never experience true love or they are only disappointed by the few times they believe they might have found it.
There are lives lived in torment or perennial discomfort versus those lived in relative serenity. Some lead a life strewn with toughness, abuse, intolerance, while others mainly meet calm and peace on their path.
Not all human beings endure such extremes, that is true. Actually, most individuals float through a sort of mediocre existence where nothing really "strong" ever happens. No deep feelings, no exceptional happenings, just a normal routine with the usual little joys and upsets, ups and down etc.
Can a satisfactory answer ever be found to the starting question?
When they say that Life is a Mystery, they (whoever they are) are not joking!
