What are the four noble truths according to the ancient Sanskrit manuscript from Nalanda dated between 700 and 1100 CE?
The first truth identifies dukkha as an innate characteristic of transient existence where nothing is forever. The second truth points to samudaya or origin as the cause of this suffering through thirst, desire, longing, and craving for attachment. The third truth offers nirodha which means cessation or ending of that attachment. The fourth truth presents marga as the road or path leading to the confinement of desire.
