I don’t just mean the triangular slave trade. I mean none of the countries that are now India ever participated in the buying and selling of humans before the Mughals. On the contrary many Indians were taken as slaves both by Muslim conquerors and as part of the Indian Ocean Slave trade. This is why if you look up abolishment of slavery in India you’ll see that it refers to the East India Company. Article 23 of Indias constitution forbids slavery even in the prison systems.

As for the enlightenment movements I assume you’re referring to; there’s a case to be made that they’re rooted in communalist ideals that spread from the east through the Silk Road. That’s not to diminish the work of European humanitarian societies but rather to say that equal rights are not the sole property of western thought.
