Acharya Prashant addresses the confusion between biological tendencies and the nature of human restlessness. He explains that while tendencies are indeed preset patterns of chemical reactions, the suffering experienced by the individual is not. The speaker clarifies that the conscious mind, or the 'incomplete I', mistakenly associates with these chemical tendencies in a futile search for fulfillment. He argues that if restlessness were purely chemical, it could be neutralized by other chemicals like material possessions or substances; however, because the self is not chemical in nature, material solutions inevitably fail to provide lasting peace.
