Shri KRS,
So, do you mean that the establishment of the whole family and social structure through all human evolution process resulting to what we have presently established to define family and society was a total failure?? It was all crape that lead to establishment of family and social living style backed up by legal instruments?
The colors of olden days relationship, love, expression of love etc..etc that you and other members are highlighting, to justify the current trend was not just the monopoly of Indian Culture BUT was there among all human species across the globe. When humans came into existence, were living in caves and no current national boundaries and civilizations were existing, humans definitely might have had crude living style without any family and social system. Humans gradually developed realizing the pros and cons of their living style, civilizations started to emerge, still people had all sort of expressions and actions (viz. gandharva kalyanam, chinna veedu, devadasi etc) and in due evolution process, finally established the definition and values of human living withing the frame work of Family and Society. When still some of this monkey minded humans didn't improve and made hell of fellow humans (spouse, other is society etc), law and order has to be improved and tightened.
What for was all these things done?
Can a wife accept her husband to have chinna veedu because in by gone days males had one?
How many families were happy and safe where husbands had Chinna Veedu set up?
Can a Father accept her daughter be a devadasi and feel proud of it because in those days devadasis existed and Men used their services?
Can we say that "live in relationship" is the most desirable living style without the need for commitment that family set up demands, because its the natural expressions of love and fulfillment of emotional and physical need of the human species?
Just because "live in relationship" as basic expression of love and need of physical fulfillment is adopted by western world, and the same have been gradually adopted in India, should we need to consider it as one of many changes in the society and thus has to be accepted with pride and pleasure? By justifying it with the living styles of by gone days in India/among Hindus or across the world among human species?
If the society is changing, then Yes, its changing and we can't do anything abut it. BUT, glorifying it and justifying it would show the deteriorating and rewinding status of human evolution.
