Siddhartha embarked on a mission that human civilization has been on since its inception – How to overcome pain and suffering in human life. Siddhartha was perhaps the first scientist on the planet who wanted to address pain and suffering at their roots. While every other thinker from every other religious traditions speculated on the goals of life and afterlife, such speculative queries were nonsensical for Siddhartha for in the mold of a true scientist, he saw no evidential basis for them. Siddhartha didn’t even query what is pain, and where does it come from. He directed his query on how can pain and suffering be removed, an enquiry no speculative philosopher had undertaken before.
