Spiritual Perspective Inspired by the Teachings of Sant Rampal Ji Maharaj

Followers of Sant Rampal Ji Maharaj believe that while robotics and artificial intelligence represent remarkable achievements of human intelligence, technology alone cannot provide lasting peace, freedom from suffering, or the ultimate purpose of life. According to their understanding of His teachings, scientific progress should be accompanied by spiritual wisdom, ethical values, compassion, and responsible conduct. They believe that true spiritual knowledge (Satgyan) helps individuals use technological advancements for the welfare of humanity rather than for destruction or selfish gain. From this perspective, robotics can improve human life when it is guided by morality, kindness, and a commitment to serving society. Those who wish to understand, according to these teachings, the real purpose of human life are encouraged to read the book “Gyan Ganga”, written by Sant Rampal Ji Maharaj.
