An analyis
The memory in the Subconscious Mind
is unlimited. It stores every thought we have ever had. Every sense is also stored there from sight and feeling (or touch). Every emotion is stored in the Subconscious Mind. So Chandra's conscious recalls the memory of Nandini in his distress.Yes ..Nandini always lurks in his mind(with love or hatred?)
The Subconscious Mind cannot determine or differentiate a real Nandini from an imagined thing. So his reasoning responds to the imaginary visualization of her with the sword
Lamentation and desolation... his feeling of resentment and failure over the loss of the battle for the second time was brilliantly and illustriously expressed by Rajat.
Guru and disciple
When the guru's guidance is of a pure nature, the disciple will never fail Here Guru Achaaryaa has a mission to fulfill and the disciple receives the mandate . Both trust each other, permitting communion of thought and feeling. Because of this interrelation,Acharya says ..Chandra does
Chandra seems to have no planning or thought of his own but fully manoeuvred by Chanakyaa and this aspect is going to be crumbled by Nandini in future.
Being on the same wavelength if two people are on the same wavelength(in extreme love or hatred), it is easy for them to understand and agree with each other harmoniously It means that Chandra and Nandini are similar in thinking at that very precise moment.(reminiscing over the full moon) . It just means both have the same opinion on their marriages subconsciously.
By this, CN team often want to specify and remind us of their future union and the upcoming hate-love journey.
