How did the geography of the Indian subcontinent during the reign of the Gupta contribute to the movement of the people and ideas?

The geography of the Indian subcontinent during the Gupta period, characterized by diverse landscapes including mountains, rivers, and plains, facilitated trade and cultural exchange. The extensive river systems, such as the Ganges and Indus, served as vital trade routes, promoting the movement of people, goods, and ideas. Additionally, the relatively stable political climate under Gupta rule, combined with well-established trade networks, enabled the flourishing of arts, science, and philosophy, allowing ideas to spread more freely across regions. This geographical and political context contributed significantly to the cultural and intellectual achievements of the period.
