Our great teacher, The Supreme Buddha, told Venerable Ananda Thero one day โ€œdear Ananda, you might think one day when I passed away, that your teacher is gone to past now and this Dhamma is of a teacher who has passed away. Dear Ananda, you shouldnโ€™t think in that way ever. Ananda, you need to consider the Dhamma and Descipline that I taught you as your teacher.โ€ This indicates that even after the death of our teacher, but if Dhamma is still available, we still can see him at any time by learning and practicing Dhamma he taught us with a great compassion. Furthermore, we should not become sad by thinking about the pass away of our teacher, but practice Dhamma. Buddhaโ€™s teachings are still being protected in its pure form in Tripitaka. This means, we can still develop the path to realize Dhamma by practicing it in a similar manner just as when the Buddha was alive, even at this time period. Tripitaka is important because of this important reason.
