Willingness to learn
Learn to give. There is immense joy in giving. Very few can understand this. Learn to resign to the will of God. There is indescribable peace in self-surrender. Very few can realize this. Learn to discriminate. There is ineffable bliss in discriminating between the real and the unreal. Very few can recognize this. Learn to be dispassionate. There is eternal satisfaction in cultivating Vairagya. Very few can know this. -Swami Sivananda.
