Acharya Prashant clarifies the classical and scriptural definitions of theist and atheist, moving beyond common misconceptions. He explains that a theist is one who acknowledges a truth beyond the sensory world and mental experiences, while an atheist is someone who believes that only what is perceived through the senses and mind is real. According to him, theism is fundamentally linked to the acceptance and understanding of Vedanta, rather than a mere belief in God or temple attendance. One who identifies solely with the physical body and material existence is considered an atheist, whereas one who understands the illusory nature of the world and realizes their true nature as consciousness is a true theist.
