If you are wondering how a gesture can mean multiple things, then I must tell you it all depends on the context. And truly master dancers and composers know how to tell two or more stories with one dance!
I regularly read something called "Vaishnava Padavali" which are ancient Bengali poems about Krishna and Chaitanya, but at the same time they convey very deeper meanings.
And it is not like metaphors in other languages, where one meaning is "hidden", the second (or third) meaning hides in plain sight.
If you interpret the meaning of a word in one way, you get one meaning, and if you do it another way, you get another. And you can string together multiple storylines and messages from one piece of text.
Let me give you an example- "Varshaa" in Sanskrit means monsoon. And "Varsho" means a year- it means the amount of time in which there is one monsoon. And again, "Varsho" are also mountains where clouds collapse to and brings monsoon. So, depending on the context (or multiple), "Varsho" could either mean a mountain or a year.
A man took it up a notch- Sandhyakar Nandi, who wrote a whole epic, which is a retelling of the Epic Ramayana on one interpretation, but is the life of Pala Emperor Ramapal on other.
In the same way, dance gestures can mean multiple things based on your interpretation. And different interpretations run parallely, together.
Sanskrit is a language with metaphors built-in in the language.
The entry barrier is extremely high, but Sanskrit poems, plays, and epics are one of the most profoundly intellectually stimulating pieces of text in the world.
