Difference between Dialogue and Monologue

I have two objectives in making this video. Students will know the difference between dialogue and monologue. First half is in the form of dialogue and second half is in the form of monologue ( narration).
Here a painting of a tree has been taken. If we look at it instantly, it seems to be like a tree without leaves , flowers and fruits. But if we observe carefully, we can see Vamana, one of the avathara ( incarnation) of Lord Vishnu. So it reveals, if we look at things, superficially, they may appear in one way, but when we have deep insight it may appear in different way. The painter's great intention will also be revealed in this video.
Please watch the video completely, like , subscribe and share it.
Thank you friends.
