In the beginning, during the Golden Age (Kṛtayuga), between the reign of Svāyambhuva Manu, and with the onset of the Silver Age (Tretāyuga) during the time of Vaivasvata Manu,
ग्राम्यधर्मप्रवृत्ते तु कामलोभवशं गते । ईर्ष्याक्रोधादिसंमूढे लोके सुखितदुःखिते ॥ ९॥
When people became engrossed in worldly duties, driven by desires and greed, overwhelmed by jealousy, anger, and other delusions, the world was filled with both happiness and sorrow.
