The idea of a self-transformative process leading to a better self is probably at the root of spirituality. It suggests the possibility of a higher form of happiness, inseparable from a state of moral perfection, an accomplished wisdom synonymous with true and perfect humanity.
This lecture presents a summary of Ostad Elahi’s thoughts on what he calls the process of spiritual perfection. A process that fulfills the purpose of every being, which is to return to its Origin and thus reach the state of Perfection; it is driven by precise laws and dependent on specific means, such as human beings’ voluntary efforts to shape their thought and develop divine virtues.
