佛遺教經論疏節要 1.403

1.403

The four truths are what practitioners constantly contemplate and base their practice upon; therefore he encourages asking. Suffering is the shifting oppression of the eight tribulations; origin is afflictions and karma drawing forth retribution; cessation is the two liberations free from fetters; path is the three trainings capable of penetrating through. If one has doubts regarding these, how can one contemplate and initiate practice? The Buddha is now about to enter extinction, so he encourages asking quickly.
