Because suffering is fundamental, there is a fundamental cure for it as well. That cure is saddharma: real (sat) dharma (truth). Real dharma can actually cure fundamental pain; that is why it is known as truth. It is genuine dharma. Practice is fundamental. It is a genuine cure. You have a genuine ego and genuine suffering, with cures to match.
