Sariputta and Maha-Moggallana were such wonderful disciples that the Buddha said the assembly of monks appeared empty to him after their death. It was marvelous he said, that such an excellent pair of disciples existed. But it was marvelous, too, that, in spite of their excellence, there was no grief, no lamentation on the part of the Master, when the two had passed away.
Therefore, inspired by the greatness of the two chief disciples, may a dedicated follower of the Dhamma strive to be his own island of refuge, have the Dhamma as his island of refuge, not looking for any other refuge, having in it the powerful help of the Four Foundations of Mindfulness (Satipatthana)! Those who are thus filled with keen desire to train themselves in walking on the Noble Eightfold Path, they will certainly pass beyond the realms of darkness which abound in Samsara. So the Master assures.
