The 44 Paths of Debate (Vāda-Vivāda): A Comprehensive Overview
In the Eastern philosophical tradition, especially within Nyaya (Logic), debate is not merely a verbal contest but a disciplined pursuit of truth. The art of dialectics involves 44 key elements or “paths” that guide the proper structure, procedure, and principles of reasoning. Mastery of these principles ensures that debates are rational, purposeful, and directed toward knowledge rather than victory alone.

Karma (Action)
The five types of motion or activity—ejection, attraction, contraction, expansion, and locomotion.
