Why is it critical to have an open mind with everyone?
It is quite a common occurrence that stories of the Divine are narrated and heard by gatherings of thousands. But Jnana (wisdom) can be achieved only by placing complete faith in what is heard. That faith must result in a cleansed mind, a pure heart. Whoever listens to the Lord's narrative and imbibes the nectar therein with a heart bubbling over with yearning for the Divine, with unshakeable faith in God, they will attain constant joy and Self-realisation. This is beyond the realm of doubt.
