It's even important to realise that most of ancient texts , ancient meaning here pre 500 BC are so old that the context they probably are centred around got lost in passages of time.
So all you have left is a piece of a wider puzzle and although translations are done , I swear some of these Upanishads especially oldest ones are so riddlesome it takes a nice context to understand them.
For instance , brihadaranyaka (big forest) Upanishad , one of the oldest , starts with mention of a sacrificial horse , metaphor for creation.
While today the text is almost universally taken as a vedantic and spiritual philosophical treatise, it's important to remember this upanishad itself is a text within another brahminical ritual text called "shatpatha brahman".
So it might not have been a ritual-less, philosophy oriented text 2500 yrs ago.
Point is : if the context and culture of the scripture is lost , it will become very difficult to retrieve its original message.
Take in terms of Guru Granth Sahib, if suppose all traces of bridal culture were lost , how would one make understanding of suhagan concepts in GGS.
Why do you reckon that's become a trend; this desire to dodge certain responsibilities and perpetually extend adolescence? I don't think it's something that's unique to us, by the way. I think it's happening to males across the world.
Maybe a frustrated or petulant reaction to the slipping of the veil that we do in fact live in a female-oriented society with its requisite values (despite what the TV and other sources try to gaslight us into believing otherwise)?
