Acharya Prashant addresses a question about the fire ritual 'Agnihotram' by using an analogy. He asks the questioner to imagine her son failing a science exam and justifying it by saying he studied science diligently, but from a temple priest. Just as one would find this absurd because the source of knowledge is inappropriate for the subject, so too is it absurd to seek scientific outcomes from religious rituals. If the matter at hand is scientific, relating to matter, one must refer to scientists and scientific texts, not to priests and scriptures. Applying this to the ritual, Acharya Prashant states that if the concern is about gases and the environment, one should consult a scientist or an environmentalist, not a religious figure. He dismisses the notion that burning ghee, dung, and wood can purify the atmosphere, explaining that the chemical reaction produces harmful gases like nitrous oxide, carbon monoxide, and carbon dioxide, which contribute to climate change and air pollution. He calls such beliefs "scientific superstition" and states that this kind of "science" originates from unreliable sources like WhatsApp and YouTube, not from proper scientific books or research journals. He emphasizes that scientists are not found on YouTube; only pseudo-scientists and scientific superstition can be found there. Acharya Prashant clarifies that the domain of religion is not material. Religion does not deal with gases, fire, oxidation, or even physical health. He points out that great spiritual figures like Ramana Maharshi, Ramakrishna Paramahansa, and Jiddu Krishnamurti all died of cancer, and Gautam Buddha died of a stomach ailment. Their bodies, being material, were subject to material laws. No religion can save a person from carbon monoxide. The body is material and will react to material just as a molecule reacts with a molecule, regardless of one's spiritual state. He concludes by defining the rightful domain of religion, stating that it deals with only one fundamental question: "What is this 'I' (ego), what is it up to, what does it want, and why does it suffer?" The purpose of religion is the liberation of the ego from its suffering. Citing the Bhagavad Gita, he explains that the real meaning of 'Yagya' (sacrifice) is to devote one's actions to the Almighty, not the gross, material act of burning things. When religion is found discussing material things like food, clothing, or planets, it is not religion but a sham or tribal superstition, propagated by those who have no respect for true religion.
