Acharya Prashant explains that human suffering arises from the ego's insistence on being the 'doer' of actions. He clarifies that if one believes they are the cause of their actions, they must also bear the consequences and the resulting suffering. He challenges the notion that an individual has the power to act against the divine will, suggesting that even the ability to reject the truth is a gift of 'Maya' or free will. To be free from suffering, one must surrender the sense of doership and realize that actions often happen spontaneously or due to circumstances rather than personal intent. He emphasizes that thinking and constant mental deliberation are what solidify the ego as a doer, whereas true life happens without the interference of thought, much like the beating of a heart.
