Nagarajuna

The fourteenth patriarch was the Venerable Nagarjuna. Once the thirteenth patriarch paid a visit at the request of a Naga king and received a wish-fulfilling jewel. The master [Nagarjuna] asked, "This jewel is the best in the world. Does it have a form or is it formless?" Kapimala replied, "You just understand having form and not having form, but you do not understand that this jewel neither has form nor is formless, nor do you understand that this jewel is not a jewel." Hearing this, the master was deeply enlightened.
