We know that natural cures are passed from one generation to another because Daadi mentions in her letter that she learnt these cures from her grandmother when she was a child. Now, she is sharing the same knowledge with her grandchildren, Vikram and Vaibhavi.

This shows a continuous chain of traditional knowledge being handed down through generations within families. Daadi writes: 'When I was a child, I learnt them from my grandmother. She used to find home remedies for most of the weather-related common illnesses.'

This statement demonstrates that knowledge of natural remedies has been preserved and passed down through generations, from grandmother to Daadi to her grandchildren. The chapter clearly shows intergenerational transfer of knowledge.
