First the depth and clarity of thinking by ancient and medieval Indian scholars writing in Sanskrit in relation to key philosophical and existential questions is extraordinary. Personally I am currently inclined to think that the advaita vedanta tradition may have the most accurate understanding of the nature of consciousness I have yet seen. Moreover this tradition is largely based on purely logical arguments, which, while perhaps not 100% convincing to a modern reader, are I think definitely worth exploring.
The above points are perhaps not unrelated to certain features of the Sanskrit language itself, which seems to have a logical structure that is rare or unheard of in other natural languages. The existence of such structure is in large part due to the work of Panini 2500 years ago, as mentioned in the article, but also to later followers who developed a register of Sanskrit that can be compared to modern frameworks for knowledge representation, as discussed in this paper: https://ojs.aaai.org//index.php/aimagazine/article/view/466.
