For example, please tell me:
* What specific time period or artistic style are you referring to? (e.g., Ancient India, Mughal art, contemporary Indian art).
* What type of art are you interested in? (e.g., sculpture, painting, textiles).
* What specific features are you referring to? (e.g., the shape of the abdomen, the curve of the chest, the presence or absence of musculature).
Once I have this information, I can provide a more specific and relevant answer about what experts think the soft rounded form of the torso signifies in Indian art.
For example, if you're talking about sculptures of goddesses from the Gupta period, experts might say that the soft rounded form represents the idealized feminine form, fertility, and abundance.
Please provide more details so I can give you a more accurate and insightful answer.
