Never mind whether you are in a factory or in hell, in a shack or in a skyscraper — it doesn’t matter. Just go on chanting Hare Krsna, Hare Krsna, Krsna Krsna, Hare Hare / Hare Rama, Hare Rama, Rama Rama, Hare Hare. There is no expense, there is no impediment, there is no caste, there is no creed, there is no color — anyone can do it. Just chant and hear.
