But it takes more than just practice to arouse bodhicitta. Other supportive measures are also needed, such as learning the merit of bodhicitta, studying and contemplating the relevant Mahayana texts, accumulating the most possible merit, etc. Without doubt, the most important is to cultivate the Four Immeasurables—loving-kindness, compassion, altruistic joy and equanimity. If we can practice in this manner, arousing bodhicitta would not be a difficult task after all. For people who do not practice, it is indeed very difficult. Comparatively, those who are diligent will not find it quite so hard. In any case, all we Dharma practitioners must get pass this one hurdle before going further down the path to liberation.
