Mistaking spiritual focus as old-fashioned is unfortunate
If people are advised not to collect too many goods, eat too much or work unnecessarily to possess artificial amenities, they think they are being advised to return to a primitive way of life. Generally people do not like to accept plain living and high thinking. That is their unfortunate position.
Human life is meant for God realization, and the human being is given higher intelligence for this purpose. Those who believe that this higher intelligence is meant to attain a higher state should follow the instructions of the Vedic literatures. By taking such instructions from higher authorities, one can actually become situated in perfect knowledge and give real meaning to life.
