Acharya Prashant discusses the dangers of scientific and material progress when it is not accompanied by spiritual growth. He points out that human exploration has historically led to colonization and exploitation, citing the examples of Africa, Asia, and the Americas. He questions the current ambition to colonize Mars, arguing that it is a wicked proposition to destroy Earth and then seek refuge for a wealthy few on other planets. He emphasizes that knowledge becomes extremely dangerous in the hands of those with wrong intentions, using the development of nuclear weapons and the character of Ravana as examples. While science has brought benefits like medicine and improved transportation, it has also brought humanity to the brink of destruction through overconsumption and environmental devastation. Acharya Prashant asserts that spirituality is essential to clean the human mind, comparing a person with scientific power but no spiritual restraint to a monkey with a sword. He notes that while material progress is accelerating, spiritual progress is declining, leading to an imbalance. He highlights India's high rate of deforestation as a consequence of using scientific power for mindless development. To measure spiritual progress, he suggests looking at indicators such as per capita meat consumption, the treatment of nature and animals, social intolerance, and the prevalence of superstition and hypocrisy in the name of religion. He concludes that without internal purification, humanity will use its increasing power to cause its own downfall.
