Sant Rampal Ji Maharaj’s Teachings: The Spiritual Aspect of Health and Healing
Medical Science Addresses the Body, Spiritual Wisdom Heals the Soul
Sant Rampal Ji Maharaj explains that although modern medical science has made great strides in identifying and treating physical ailments, genuine and enduring healing can only be achieved through spiritual understanding.
He clarifies that real health encompasses not just the body, but also mental tranquility and spiritual cleanliness. Many health issues, particularly chronic and untreatable ones, often stem from karmic effects of previous lives. While medications may offer short-term relief, they cannot eradicate the root of suffering linked to past actions.
Naam Diksha: The Path to Karmic Purification
Sant Rampal Ji Maharaj states that only the authentic spiritual journey can clear these karmic obligations. By receiving Naam Diksha (spiritual initiation) from a Complete Saint and engaging in true devotion through mantra chanting and adherence to scriptures, individuals can alleviate both physical and spiritual pain. This practice purifies the soul, fortifies the inner self, and can even lead to healing from ailments that resist medical intervention.
Living Righteously for Lasting Wellness
He highlights the significance of leading a moral and disciplined life—avoiding substances, violence, dishonesty, and unethical actions. Such a lifestyle not only improves physical health but also fosters mental clarity and spiritual development. Preventive health measures in public health closely align with spiritual values of cleanliness, compassion, and self-discipline.
The Union of Science and Spirituality
Sant Rampal Ji Maharaj endorses the application of medical science and encourages individuals to seek treatment when necessary. Nevertheless, he emphasizes that science has its boundaries. While it can heal the body, only spiritual wisdom and devotion to the Supreme God can mend the soul and provide true tranquility. For holistic well-being, He teaches that science and spirituality must work together.
