Acharya Prashant explains that faith is strengthened through repeated testing and experience. He suggests that one must allow the internal conflict between faith and illusion to play out like a wrestling match rather than avoiding the situation. By repeatedly taking risks and making decisions based on faith, one realizes that faith consistently prevails over illusion. This process takes time because the mind requires constant evidence to reach a conclusion. He clarifies that the victory of faith does not guarantee that worldly misfortunes, such as losing a job, will not occur. Instead, faith means that even if the worst-case scenario presented by illusion comes true, one remains internally unaffected and undisturbed. True faith is the state of being in bliss regardless of whether the external outcome is perceived as good or bad, knowing that one has the strength to endure anything.
