Spiritual Health is a very important concept in Spirituality. The most important components are spiritual outlook, spiritual discipline, our spiritual philosophy which is realized after many years of spiritual commitment. It is spiritual health that decides our destination beyond this body-mind. It is a parameter that decides the vehicle called spiritual body that remains with us for eternity after we qualify for it, on maintaining a high-level of spiritual health.
Sanatana Dharma is the most advanced science, which is far beyond the reach of the material sciences which we know off. There are many dimensions of consciousness which lie far beyond the five senses which function only in the earthly platform. When our perception is enhanced through specific processes,of Sanatana Dharma we can develop the ability to travel to those dimensions.
