There is an ancient culture, whose central point was in india some thousands of years ago. That culture produced many works of history and prophecy collected in books called “Poorana”. In the Poorana named “Vishnu” there is a quote from a sage named Parashara (the founder of Ancient Astrology, by the way). He says:
The age of iron [our current age] is black and full of problems, but has one amazing virtue: spiritual enlightenment can be had by an extremely simple method: pronouncing the names of Vishnu [Godhead].
Even without spiritual motivation, one who pronounces those names will lose their ill karmas! By chanting the names of Vishnu for just one day and night a person living in the age of iron achieves what it takes ten years of deity worship to achieve in the age of brass, what it takes a hundred years of sacrifice to achieve in the age of silver, and what it takes a thousand years of meditation to achieve in the golden age!
The only sadness is that age of iron people will scoff at this idea.
The age we live in is a mine of iron and silicon and electricity and soot. But there is a vein of diamond in a neglected tunnel.
