Jain Philosophy
The three pillars of Jain philosophy are Anekantavada (many-sidedness of truth), Syadvada (conditional predication — 'in some respects'), and Nayavada (partial viewpoints). These together form one of the most sophisticated epistemological systems in world philosophy, asserting that every claim about reality is valid only from a particular standpoint. Jain cosmology is also unique: the universe is alive with infinite souls at various stages of evolution, all eternally capable of liberation. No god created it; it runs on karmic mechanics.
Pick one belief you hold strongly. Now genuinely argue the opposite for 60 seconds — not to change your mind, but to honour the reality that every truth has another face. This is Anekantavada.
Best for philosophical study in the early morning hours.
