"Buddha said in the Prajnaparamita Sutra, that the bodhisattvas should never abandon the dharma. By this he meant that if a bodhisattva were to think, 'Oh, this person is only teaching the Shravakayana, that person is teaching only the Pratyekabuddhayana,' then even that can be considered as abandoning the dharma, which is one of the most hideous nonvirtuous actions. Thinking in this way means you have developed an attitude, considering Mahayana as the supreme and all the other vehicles as lesser. An ecumenical or nonsectarian attitude to the teachings of the Buddha is so much required—especially if you are practicing the Mahayana path."
