Charak Samhita
भवतश्चात्र- युगे युगे धर्मपादः क्रमेणानेन हीयते। गुणपादश्च भूतानामेवं लोकः प्रलीयते ॥२५॥
At the end of the satyayuga, however, some affluent people started gaining heaviness in their bodies due to over-indulgence in food. They started suffering from fatigue in lieu of this. Fatigue gave rise to laziness, and laziness made them to accumulate things; accumulation led to the attachment for these things and attachment resulted in greed.
