Acharya Prashant clarifies that sex is a concern of the body and not of the self. He explains that sex is neither a helpful tool for liberation nor a distraction, but rather a biological function of Prakriti aimed at procreation and the continuation of the cycle of birth and death. He emphasizes that when one's primary concern is truth and liberation, sexual thoughts naturally recede into the background. He uses the analogy of a stove in a neighbor's kitchen to illustrate that the body's urges should not be mistaken for one's own spiritual needs.
