500?!

From the Vision Quest Tarot, the Five of Wands; from the Bird Cards/Ascension to Paradise Decks, Raven:

It is said that after Buddha's death, 500 followers (who had memorized Buddha's discourses) met to agree on what should be written down as the wisdom he shared. I find that unimaginable; it's hard to get even a small group of people to agree with another's opinion on how something should be done. Of course humility plays a part - we must be willing to give the other enough space to share what they know and sincerely consider what they say. The intelligent Raven is known for its ability to solve problems as well as other cognitive skills such as imitation and insight. In sync with the Five of Wands, relationships between common ravens are often quarrelsome, yet they demonstrate considerable devotion to their families. Perhaps the message from this bird is to not to forget what is of utmost importance and our ultimate purpose.
