You know what ! Sage yajnavalkya , 2700 years ago ! said the same thing in one of his works which BTW now are embedded inside yajur veda .
All love is love of the self (soul) ! He said "Man loves not his wife, his children , but loves himself"
We love ourselves, but don't realize who that ourselves is ! one who knows this is liberated .
"And one who dies and passes from this world without knowing himself is someone deserving of pity " (quoted from some upanishad)
You have lived the harshness of life , would your conclusions today have been any different if life gave you a softer , creamier side ?
What happens to those men and women, I wonder, who get what they want in life ? who live a very comfortable life ..
do they ever reach the conclusions you reach. What kind of inferences from life they draw , I wonder.
