Concept:
Rabindra Nath Tagore was a versatile playwright whose works often blended symbolism, music, and social critique into a cohesive poetic experience.
Step 1: Differentiating between the authors' works.
Daakghar (The Post Office), Raktkarbi (Red Oleanders), and Bisarjan (Sacrifice) are all famous plays written by Rabindra Nath Tagore. Pagla Ghoda (The Mad Horse), however, was written by the modern Indian playwright Badal Sircar. It is a landmark play in Indian theatre history, focusing on memory, guilt, and male-female relationships, and is distinct from Tagore's symbolic style.
