And I've only watched the first few episodes, so this list will be brief.
- Kumud jumps into the water to retrieve the pearl in the very first episode. Later on, she attempts to commit suicide by drowning.
- Kumud makes Kusum dress up as her and approach Saras. Near the end of the story, she forces him to marry her.
- Saras's devotion to his religious (adhyatmic) studies later manifests in his living in Vishnudas's ashram.
- Saras saves the young boy from drowning. And then he also fills the water-pots from the well. His power over water is symbolic of how he will later use water as a means to get away from his past i.o.w. traveling to Suvarnapur.
- Saras's charity and social service later on become his primary objects of devotion.
- Vidyachatur says something along the lines of "Yeh dono saare riti riwaaz todne waale hai." And YES, they do! Saraswatichandra goes on to become one of the greatest social workers.
I'm sure there's many more that I missed out on. Anyone want to add anything?
