Finally, the Karmapa cautioned against complacency. There is always the danger that we will fool ourselves into believing that we are Buddhist practitioners when we are not.
The difference between the Foundational Vehicle and the Mahayana is not a question of lesser or greater value between the two, he explained, but rather a question of our own capacity to practice the Dharma, and how much responsibility we are able to assume. If we are unable to carry all the responsibility of the Mahayana, we should practice the Foundational Vehicle. And even that is too difficult for many people.
Dharma practice is not about external appearances but about what is happening in our minds. Referring to a popular Chinese text, the Diamond Cutter Sutra, His Holiness pointed out that though this is classified as a Mahayana sutra, whether it becomes a Mahayana practice or not will depend on the state of mind of the individual.
“Whether we are Hinayana, Mahayana or even Buddhist, depends on the state of our mind when we practice and not on the texts we use,” he commented. ”We need to continually correct and revise our minds and examine ourselves.”
